I've noticed that when attacking an object (e.g. a barrel) with a fury-generating skill as a Barbarian, I generate fury as if I would have attacked a monster. Attacking a barrel with a spirit-generating skill, however, does not generate spirit.
My question is, when do resource-generation skills actually generate resources when attacking an object?
- Does it only depend on the class?
- Does it depend on the specific skills used?
- Does it matter if the object is a red-highlighted one (e.g. a barrel) or a non-highlighted one (e.g. a tombstone act 1 graveyard)?
