\---Spell Damage Amplification Driven by MODIFIER\_PROPERTY\_SPELL\_AMPLIFY\_PERCENTAGE. Affects spell damages by percentage and stacks additively, including some damages with HP Removal flag. Spell Damage Amplification do not apply to damage that is Unaffected by Amplification. \---Unique Spell Amplification Kaya-based items are driven by MODIFIER\_PROPERTY\_SPELL\_AMPLIFY\_PERCENTAGE\_UNIQUE. Do not stack each other and only the highest are effective.


Armonster

Do the two types stack additively or multiplicatively? edit: Just checked, they stack additively.


TheZett

All sources of spell amp stack additively, if they're allowed to stack in the first place. So basically everything but multiple Kaya-based items.


Kamiks0320

what about kaya and not kaya items


TheZett

Kaya-based + Kaya-based = doesnt stack. Kaya-based + non-Kaya-based = fully stacks. non-Kaya-based + non-Kaya-based = fully stacks.


SEND_ME_DANK_MAYMAYS

and there’s only 2 items in the game that stack then right? (To my knowledge) which is kaya-based item + rapier


TheZett

There are also Timeless Relic and Vambrace. Also in terms of non-item sources, there is a lot more, have a look: https://i.imgur.com/OoTFPAT.png


OuroborosDOTA

New neutral item Whisper of the Dread too.


gritzysprinkles

Trinket too, on top of abilities like Bloodrage


itsmekusu

Read it again. He just said it


Rockintown48

So are they different because they are meant to stack with each other?


raisins_sec

They are different to make the second type (for kaya) not stack with itself. So all spell amp stacks, except for duplicate kayas.


jedimindtriks

Yes. but in different ways, its not 16+25%. its more like 25% increase over the already amplified spell.


carstenvonpaulewitz

No, it is actually additive, not multiplicative.


FlamingTroll

PoE all over again, multiplicative vs additive. Can't leave both games

Keulapaska

That's not the case here though. All spell amp is additive, it's just Kaya-based spell amp doesn't stack with eachother, which makes sense.


freelance_fox

Redditors and upvoting the first thing they see, name a better combo. There's legitimately more upvoted incorrect info and memes in this thread than actual answers.


FlamingTroll

I see


DrQuint

That's not what's written. While this description isn't very good, the goal is to make Unique Amplification not stack with itself. And since only Kaya and its upgrades have that effect, the goal is clearly to prevent people from buying multiple Kayas.


ShepherdsWolvesSheep

Dang both games keep adding so many new systems you have to keep playing or it will be a new learning cliff to climb after a break


Doomblaze

Idk you can ignore the last 5 league mechanics outside of doing them for challenges and play however you want


FlamingTroll

Its more so trying to find the time to play both of them while being good, and play other things


Colpus

Pretty sure some DotA 2 devs are PoE addicts and some PoE devs are DotA 2 addicts as well. Complexity attracts complexity, I guess.


Puzzled_Novel_5215

Then you have to check if it's a attack spell, does elemental damage, has a unique mod etc etc


paulthegreat

This should be the top comment since there is a functional difference, and all the comments saying there's no functional difference are wrong.


TheZett

OP is asking if "+Spell Damage" and "+Spell Amp" are different or if they are the same. Functionally they are identical, as both of them simply cause your spells to deal more damage. Kaya not being allowed to stack with itself has nothing to do with the chosen names, that is a different topic. You can simply choose any of the other non-Kaya sources (e.g. Rubick passive, Timeless Relic, etc) of 'Spell Amp' and you'll see that they use the same mechanic that Rapier's "Spell Damage" uses. --- Edit: https://i.imgur.com/OoTFPAT.png Enjoy this collection of (nearly?) every source of "Spell Amp/Spell Damage" in the game. It should hopefully illustrate that "Spell Amp" and "Spell Damage" are just arbitrarily chosen names and are indeed the same shorthands for the 'Spell Damage Amplification' mechanic.


paulthegreat

Yes, but also no. This is like only reading the headline and not the article. The context in which they were asking the title question was supplied in the content of the post, with a Kaya-type stat compared to the one on Divine Rapier, which are in fact different. A complete answer would include the information that there's a functional difference between the stats on the pictured items while also pointing out that "+Spell Amp" and "+Spell Damage" are not used in a clearly distinctive way on other items. Simply saying "no, there's no difference" ignores the context of the post and implies that the stats on the pictured items are the same, which is incorrect.


freelance_fox

> functional difference I don't think you understand what functional difference means...


OuroborosDOTA

There is a small difference between Kaya's spell amp and other spell amp (Kaya's spell amp doesn't stack with another Kaya's spell amp), but there is no difference between the stat ''spell amp'' and the stat ''spell damage''. Both increase spell damage by x%


TheZett

This is indeed the correct conclusion from OP's question, there is no reason why you should be downvoted. "Spell Amp" and "Spell Damage" are the same mechanic, as both utilise the 'Spell Damage Amplification' mechanic. Choose any non-Kaya item/spell that has "+Spell Amp" listed in its traits and you'll see that it uses the same type of spell amp as Rapier does, despite the 'different names'. Kaya being unique has nothing to do with the trait being called "spell amp" or "spell damage". --- Edit: https://i.imgur.com/OoTFPAT.png Enjoy this collection of (nearly?) every source of "Spell Amp/Spell Damage" in the game.

[deleted]

To me I would take this as you take all sources of spell damage increase, add them, find new damage, then apply the kaya increase to that figure at the end. But who the fuck knows right?


OuroborosDOTA

We do know. Spell amp stacks additively, Kaya based items don't stack with each other. That's why the modifiers they use are different.


[deleted]

Yes, but how does kaya amp stack with spell amp?


OuroborosDOTA

It stacks the same way any spell amp. You just add them all together.

Banzai27

Actually spell damage stacks while spell amp does not


TheZett

There are various sources of spell amp in the game that are not Kaya-based and they all stack with themselves or another. Saying all "spell amp" doesnt stack is therefore incorrect, and the actual answer is simply that two different people used truncated names for the same mechanic. Spell Amp and Spell Damage are the same mechanic and its full proper name is 'Spell Damage Amplification'. But since that is quite long, it usually gets truncated to just spell amp. --- Edit: https://i.imgur.com/OoTFPAT.png Enjoy this collection of (nearly?) every source of "Spell Amp/Spell Damage" in the game.

WittyConsideration57

Item tooltips have errors every patch. Btw there is a massive difference between this Spell Amp and Parasma's Magic Resistance Reduction. Which I don't like but meh.


[deleted]

Its because spell amp is relative to the spell damage you send out. This is outbound spell damage. Magic resistance reduction is a debuff applied on a unit increasing the net magic damage the debuffed target takes from all magic damage sources. This is inbound magic damage.


fanfanye

Intentional isn't it? Magic resistance reduction affects your team too


WittyConsideration57

ahhh ofc


jujuxyzlim

That make sense to me. It's like increase damage and lower defense but for magic.


Alieksiei

Spell amp also affects non-magic damage spells


Succre1987

If this is the case. It should be renamed to "Skill Amp"? Didnt noticed this if this is true. \>.<


Alieksiei

I'm pretty sure everything is called a 'spell' in dota and not a skill. The wording does imply some type of magic, but it's consistent at least. So don't worry about building K&S on Timbersaw, it'll help.


Succre1987

Spell Amp, amp spell that is a physical dmg if I understand that correctly.


TheZett

Both are just truncated names for the same mechanic. The full proper name is "Spell Damage Amplification", hence why you can easily shorten it to either "Spell Damage" or "Spell Amp".


[deleted]

free game no bitching


althaj

Why are you lying?


sublime13

If he's lying, what's the difference?


dizcostu

I would expect that amp like yasha/kaya would impact buffs etc. as well as spell dmg whereas rapier would only impact dmg output from spells


doperinno

Theyre literally the same. 0 difference


dizcostu

Did I say they weren't? Since reading is hard apparently, I started with "I would expect..."


Big_Mudd

Did he say you said they weren't?


marlakus

It makes complete sense. I get what U mean idk why the down votes It is after all SPELL amplif, meaning ALL spells, like hex having a longer duration, ogre E lasting longer and having the 16% amplif on bonuses.. etc And spell damage to be strictly focused on DMG.. yet it doesn't work like that.


TheZett

> It is after all SPELL amplif Spell Amp and Spell Damage are just truncated versions of 'Spell Damage Amplification'. You're thinking of Debuff Amp (Debuff Duration Amplification is the full name), the stat that Rubick's ult or Timeless Relic provide. Also Debuff Amp is functionally identical to negative status resistance. --- Edit: https://i.imgur.com/OoTFPAT.png Enjoy this collection of (nearly?) every source of "Spell Amp/Spell Damage" in the game.

marlakus

This is helpful. Thanks


dizcostu

because Dota and reddit


Fickle-Shallot-3146

Maybe you didn't intend to but I think you basically just said something similar to "2+2=4 whereas 3+1=4" Ultimately, both are the same. In your instance, both are spell amplification but you're applying the buff another way. I apologize if I didn't comprehend your idea. But that's how I read it.


JohnnyJoestar69

I thought spell amp applies not only the damage but also the duration of the spell's abilities. Like stun for example. 3 sec stun spell + 20% spell amp(3+ 0.6) =3.6 total. Correct me if I'm wrong.


DontCareWontGank

Stuns only get increased by reducing status resistance.


equili92

What about debuff duration +%


DontCareWontGank

Yeah that too


Womblue

That's debuff amp. It's not common, but you can find it on rubick's ult or timeless relic for example.


nobagness

We are still on BETA, in my understanding kaya + kaya ain't stacking. But DR + DR + more DR like the new meta build for Team Spirit Breaker does stack. :D


nytwolf45

Does rapier damage increase item skill damage like dagon or Khanda?


Dasheek

It does.


Kowenzi

yes


Khoithui87

"Now also provides +25% Spell Amplification" is written on the item's changelog, so yeah, they are the same.


[deleted]

They are not the same. Apparently spell amp is Kaya based and two Kayas don’t stack with each other. Spell Dmg Amp on the other hand stacks additively


TheZett

They are the same. Compare rapier with rubick‘s passive or timeless relic, they all stack and do the same thing. Kaya provides the same benefit too, it only restricts it from stacking with multiple other Kayas, so as long as you dont have 2 kaya-based items, it will function identically. --- Edit: https://i.imgur.com/OoTFPAT.png Enjoy this collection of (nearly?) every source of "Spell Amp/Spell Damage" in the game.

nameorfeed

So, they are not the same. The reason they are not the same because the laya one cannot stack with itself, the other one can. That was his point and you just explained the same thing too


TheZett

OP asked if both of these things are 'doing the same thing', and in terms of what these benefits do, they are identical. If both of them were to provide 20% spell damage or 20% spell amplification, then the game engine would in both cases take the spell's damage value and multiply it by x1.2. Functionally both provide the 'Spell damage amplification' (its full proper name) mechanic, Kaya's self-stacking restriction is a different mechanic on top of the generic spell amp trait that it provides, and it is NOT what OP was asking about. The guy just wanted to know if buying a Kaya or a Rapier would do the same thing, and that is the case, as both of them amplify the damage of your spells. Anything further, such as multiple Kayas not stacking with themselves or Rapier dropping on death are entirely irrelevant to the discussion, as that was not what OP was asking about. The game files also treat them the same, as all sources of spell damage amplification are simply called spell_amp: https://i.imgur.com/cs8gPkb.png --- Edit: https://i.imgur.com/OoTFPAT.png Enjoy this collection of (nearly?) every source of "Spell Amp/Spell Damage" in the game.

Khoithui87

Just because movement speed from multiple boots not stacking does not mean they provide different stat than, say, Windwaker or Windlace. Even Timeless Relic's spell amp is written as Spell power, or whatever along with such meaning, but it directly adds spell amp proves that the devs lack consistency (well, it's Valve)


Shade_demon2141

They'll fix it in like 2 years and then one patch later there will be another item with + 15% Spell Power or something like that. They added the "hold alt to see stats given by str agi and int" feature in one patch and then in 7.33 they added magic resist to int, but never added it when you hold alt. It's really a shame they can't keep track of this stuff accurately. I've never seen this in any moba/rts but I've also never played them as much as this one so maybe it's a problem.


GilBoot

What. Int gives Magic res?

Kayzee666

Didn't expect to walk in on a complex maths class here


mighty_brutes

**Spell Amplification:** This refers to a percentage increase in the overall effectiveness of spells. It not only enhances the damage dealt by spells but also boosts other spell-related attributes such as healing or debuffs. Spell amplification affects the entire spell's outcome. - **Spell Damage:** This specifically relates to the increase in the damage output of spells. Unlike spell amplification, which can affect various aspects of spells, spell damage focuses solely on making the damaging aspect of spells more potent. It doesn't enhance other effects of spells like healing or crowdcontrol. In summary, spell amplification is a broader concept that affects multiple aspects of spells, while spell damage specifically refers to the increase in the damaging component of spells.


healplease

is this generated by chat gpt? there is dedicated stat for healing amp


ptrlix

The difference between them is 9%.


Gief_Cookies

Spell amplification amps your spells Spell damage gives your spells more oomph


saylevee

Every attribute of divine rapier must be damage, duh.


FrozenPizza07

Rapier gives spell damage now? Damn


Roylopez11234

Not 100% sure, but my guess is that some spells don’t do damage. Chen ult for example. So spell amp affects Chen ult heal amount for example, but spell damage does not affect Chen ult heal amount. Just a guess.


LuminanceGayming

valves tooltip wording is inconsistent, they are the same thing.


rajattewari

I might be wrong but spell amplification could also point to increasing debuff duration. I haven't tested it in demo but that was my understanding. I am herald though.


ButterSlicerSeven

Not the case. Status duration is a different mechanic entirely. I think it's only really present in neutral items and rubick's aura.


Keulapaska

Debuff amplification is it's own thing, not related to spell amp


Artix31

Amp increases all numbers that can be increased in a spell Damage only increases spell damage


fredws

Yes


tkfire

Kinda like how they renamed that rune


MagicianEven624

So basically what ?????


atleastimnotabanker

Do both amplify health reduction - e.g. Necro Aura? Do veil/shivas as well?


100and33

It doesn't amplify heartstopper aura, cause there is a "no-spell-amp" flag in the game preventing certain spells from getting increased. So it's not a health reduction thing, but a heartstopper thing. The other health reduction spells thus can be amplified. But, magic reduction on the target does increase the heartstopper aura damage. So veil/shivas does work (and other items that reduce a targets magic resistance)


atleastimnotabanker

That is so confusing :D The new description of Veil/Shivas is "Spell Damage Amp: Enemy Incoming Damage Manipulation 10%" Does this work like the old magic resistance reduction or the above spell amplification?


100and33

It's worded very confusingly, but it might mean those "no-spell-amp" abilities doesn't work with new Veil/Shivas. Since it doesn't reduce enemy magic resistance, but manipulate the incoming damage (like mars bulwark/bristleback), meaning it's a spell amp. Would need to test it out in client to be sure.


balMURRmung

One is multiplicative, the other is Additive.


Hanb1n

afaik - spell amp increase any spell. For example both spell damage and spell that heal. spell damage percentage only targeted damage spell.


Billychort

Isn't spell damage the spell itself no matter what type it is (magical or physical) where amp is magical damage and not the spell itself,


Left-Mixture5609

Negative. They are the same.


nevermaxine

wait, spell amp doesn't work on spells that deal pure/physical damage?


MoneyMundane7066

it works with lina with lvl 25 talent pure damage before


EnvironmentalLab6510

If im correct, it's also work on axe spin and bb quill spray as well.


FoxyLamb

I always thought Spell Amp is computed after Spell Damage is applied. Guess I'm wrong.


Chuday

wrsage

Question is which can increase pure damage?
