Can Wolf Savage stack with Bestow Curse?

[Reduxist]

I'm asking this because the RAW for the feat only says that it creates an effect similar to Bestow Curse.

[Evilgm]

It actually says "identical", which is quite different from "similar". However, since the penalties are untyped and the sources have different names (even if they are functionally identical), they should stack.

[James Risner]

Two casts of Bestow Curse won't stack.
So depending on how identical, this identical is in the mind of your GM, it may or may not stack.

Ask your GM.
