Blizzard is doing a +50% xp weekend in Diablo 3, and I'm wondering if and how it stacks with the other xp bonus' from difficulty tiers.

On Expert

  • Additive:
    • (1+difficulty+.5)*base
    • 1k xp monster in normal now equals 2.5k xp
    • Net gain = +150%
  • Multiplicitive:
    • (base + .5*base)*(1+difficulty)
    • 1k xp monster in normal -> 1.5k xp with weekend bonus -> 3k xp on Expert
    • Net gain = +200%

the quantifiable difference really becomes apparent at higher difficulties:

On Torment IV

  • Additive:
    • (1+difficulty+.5)*base
    • 1k xp monster in normal now equals 9.5k xp
    • Net gain = +850%
  • Multiplicitive:
    • (base + .5*base)*(1+difficulty)
    • 1k xp monster in normal -> 1.5k xp with weekend bonus -> 13k xp on Expert
    • Net gain = +1200%

As players it is definitely to our advantage if they are using multiplicitive bonus instead of additive. Does anyone know which Blizzard is using?

  • Other ingame modifiers are all additive, I'd expect that xp bonus works the same way as well.

  • Am interested. I presumed it was EveryDayNetAfterDifficulty(xp) * 1.5 (1k including all regular modifiers => 1.5k)

  • The buff says nothing about bonus experience. It says experience GAIN is increased by 50%. Apr 5 '14 at 11:06

These are the numbers taken from the game interface with

Community event Buff - Your experience gain is increased with 50%

On N  0%    bonus ->   50%   Bonus Experience
On H  75%   bonus ->  162,5% Bonus Experience
On E  100%  bonus ->  200%   Bonus Experience
On M  200%  bonus ->  350%   Bonus Experience
On T1 300%  bonus ->  500%   Bonus Experience
On T2 400%  bonus ->  650%   Bonus Experience
On T3 550%  bonus ->  875%   Bonus Experience
On T4 800%  bonus -> 1250%   Bonus Experience
On T5 1150% bonus -> 1775%   Bonus Experience
On T6 1600% bonus -> 2450%   Bonus Experience

So on Normal: 1000 Exp becomes 1500 instead of 1000 (50% total increase)
So on Hard  : 1000 Exp becomes 2625 instead of 1750 (50% total increase)

Im not gonna do that math for the rest but I assume they are either perfectly correct or close within a rounding error of being correct.

In the past, it has been additive, but you should be able to check out your character sheet (inventory->details) and it will have a bonus XP percentage stat on it.
