Possess

Spellcaster can target only friendly figure except
the wizard, apprentice, or demons. The target is
possessed by a demon and gains +2 Fight,
+1 Armour, and -2 Will and counts as a demon
(it will be affected by Banish, Control Demon,
Circle of Protection, etc.). This figure may not be
part of a group activation. If removed from
the game for any reason (such as being hit by
a Banish spell), check for the character's survival
as normal. A spellcaster may only have one Possess
spell active at a time
