Talk:Effect

Stacking
The discussion of effect stacking seems either somewhat confusing or somewhat inaccurate. How effects such as strength increase stack depends on how they are scripted and how the engine applies the effects. E.g. because of how the spells are scripted (and how the engine deals with EffectAbilityIncrease), a casting of Bull's_strength will not stack with another casting of that spell, but it will stack with an earlier casting of Greater_bull's_strength. The stacking will not happen when the spells are cast in reverse. Similarly, two items of the same type with an ability increase effect will stack (up to the +12 limit), even if they are from the same type of item (e.g. Rings of Clear Thought +1 and +2) and even if they are identical (e.g. two Nasher's rings).

But, the point is that the scripting and the engine determine how/whether such effects stack, and they aren't consistently applying the rule the article seems to suggest. I wonder if it wouldn't be better to simply say, "Though ability increase effects from the same spell seldom stack, the stacking of similar effects from different sources (e.g. two sources of strength increase) is determined by how the game engine applies the individual effect."

BTW, I am not trying to say there is no way to read the article as being accurate (e.g. there may be some wiggle room in interpreting "applied from the same source"). It's just not that clear. - MrZork 04:47, April 14, 2011 (UTC)
