Total Damage % Reduction WeakAura

[Woz]

Found this thread on R&D but figured this might be a better place for the question and since a guildie of mine is asking about something like that now:

"I'm looking for a WeakAura or Addon to let me know the cumulative % of damage reduction that dynamically updates during combat.

An example would be having Bone Shield and Sac at the same time, and showing the % of damage reduction it is."

The WoW API does not group any damage reductions together. That would require you to create a list containing all damage reduction spells that exist in the game.

Unless you're willing to limit the scope to a handful of specific damage reduction buffs to keep track of, you're much better off looking for any addons that have been created specifically for this purpose.

Yeah I figured as much, thanks pnut

Here's the one I have on my Shaman. Would require updating for each of your relevant abilities.

Order of calculation doesn't matter because multiplications are commutative.

Correct formula would be 1*(1-0.5)*(1-0.3)=0.35 damage taken, or a 65% reduction.
