I would like to put 18 to 20 skill points into Summon Skeleton Mage (= 8 total magi) for the extra firepower and protection.
I am not certain if I want to max Corpse Explosion. My fishymancer has maxed Summon Skeleton, Skeleton Mastery, and 17 Corpse Explosion (8-yard radius). Amplify Damage + Corpse Explosion or Dim Vision?
