Guild Wars 2

I want to know if Superior Rune of the Eagle will stack with Executioner . Giving me 26%

Percentages don’t add up.

I couldn’t find it on the wiki but I suppose you put skill modifiers on top of rune modifiers. If your weapon has a power of 100 you would have :

eagle
100 + 6% = 106 damages
Executioner
106 + 20% = 127.6 damages

Modifiers are multiplicative… meaning you actually get more than 26% as they stack. The more multipliers the more they start to add up. Example:

• (3000 power * 1100 staff * 2.25 vault) / 3000 enemy armor

So non crit you end up with a Vault of 2475.

• (3000 power * 1100 staff * 2.25 vault * 1.2 Executioner) / 3000 enemy armor

So non crit you end up with a Vault of 2970 which is 20%. Now comes the “magic”:

• (3000 power * 1100 staff * 2.25 vault * 1.2 Executioner * 1.06 Eagle) / 3000 enemy armor

6% of the base damage is 148.5. However with Executioner factored in that Eagle damage is actually 178.2. It starts getting more obnoxious when you factor food, traits and skills in:

• (3000 power * 1100 staff * 2.25 vault * 1.2 Executioner * 1.06 Eagle * 1.1 Bound * 1.1 Staff Master * 1.07 Havoc * 1.06 Lead Attacks * 1.1 Exposed * 1.05 Forced * 1.1 Seaweed) / 3000 enemy armor

Now we are at 5489…. crit that with a strong magnitude and on a hardened opponent a thief is landing a Vault at north of 12k.

P.S. This multiplicative nature of damage bonuses is why Vault and in some cases Backstab get an OP label by a lot of players. Thieves have very strong multiplier access.

Correct, and subsequently very low static stat gains, which creates a big disparity in performance between WvW and sPvP since the stat allocations in sPvP are lower and thus there is less to multiply while static gains have a bigger relative impact on builds.
