Emulate Spell Ability...
Emulate Class Feature: Sometimes the character needs to use a class feature to activate a magic item. The character's effective level in the emulated class equals the character's result minus 20.
This skill does not let the character use the class feature of another class. It just lets the character activate magic items as if the character had the class feature.
If the class whose feature the character is emulating has an alignment requirement, the character must meet it, either honestly or by emulating an appropriate alignment as a separate check (see below).
