Forgive me if this is very basic and expressed in the rulebook. I tried to find a clear rule but couldn't.
If a Wizard tries to make a Knowledge: Arcana check on magic or an artifact with properties from one of his opposition schools, is there any sort of penalty?
Example: Wizard with School of Conjuring specialty and Opposition Schools of Necromancy and Enchantment attempts a Knowledge: Arcana check on a Robe of Bones(Necromancer gear).
