Very well. I think that the current Ronodin isn't too far above what GM Panic outlined above, and, as has been my plan all along, I will reduce stats and numbers as needed to not outshine everyone else.
Ronodin is a fairly typical 'knowledge is power' character, and strongly seeks to find magical items and to grow his own abilities such that he becomes a master mage. In-combat, he focuses on debuffing single targets, crippling them and removing them from the combat, but can also do mass debuffing or blasting if needed. Typical Wizard stuff, except that he can also use Possession at-will, giving himself a meat shield.
Out of combat, he's a master at Knowledge skills and general intelligence-based skills.
