Well, if you don't agree that the feat modifies the class ability, then there are a number of issues. First, the class ability is supernatural and thus lost in AMF. The feat is not Su (because it doesn't say it is, and is thus Ex). Big difference. Also, since you say they are different sources, then clearly they stack.Rkhet said:I can see how it could be interpreted that way, but strictly speaking, 'causes' is not exclusive. taking a feat that makes one of your class features 'cause' something does not remove the original benefit, I would think.
http://www.d20srd.org/srd/theBasics.htm said:In most cases, modifiers to a given check or roll stack (combine for a cumulative effect) if they come from different sources and have different types (or no type at all), but do not stack if they have the same type or come from the same source (such as the same spell cast twice in succession). If the modifiers to a particular roll do not stack, only the best bonus or worst penalty applies. Dodge bonuses and circumstance bonuses however, do stack with one another unless otherwise specified.
But, you claimed it wasn't a modification to a class feature. That's how you can justify -6. If it's a modification of the class feature (like I claim), then the question on stacking is irrelevant, right?Rkhet said:Modifications to class features doesn't change its type.
Good point. Thanks for that.Rkhet said:On stacking: ...
Penalties are handled the same way as bonuses. Only the worst applies.
