Obi-Wan's Spirit (A):
Obi-Wan's Spirit doesn't count toward controlling the Character arena. Prevent all damage to and from Obi-Wan's Spirit. Each of your Jedi Characters' activated abilities costs 1 less Force to play (as long as Obi-Wan's Spirit is in the Character arena). Abilities that cost 1 or more Force can't cost less than 1 Force.
