[@Lord Zee]Not unless you want to drop higher talent illusions. The one I mentioned is Succulent

He is a fencer, and illusionist so Illusionist subclass in the rogue category is probably needed, or something like it.

However it appears I am mistaken as he apparently is a warrior despite appearing to be a rogue. So mage specialization may be needed. But one could argue rogues can do something similar.
