Merc Skill Question

[Tinman]

I have two Mystics with 2 of the same skills and 2 different skills. The Petrify skill on the "new" merc works but the Poison Cloud does not. Poison Cloud is the common skill between them. So is that the way it is supposed to be? So you can't have 5 Mystics all w/ Tigers Strength.

Same skills don't stack on targets. Basicly, if a merc casts poison cloud on an enemy (or on more enemies if your merc has curse mastery), those enemies cannot be affected by any other poison cloud.
