Effectiveness
s = Spawning Power, c = Communing example: s4c5 = Spawning Power at level 4, Communing at level 5 One Use is depleted when the spirit loses life to use its power. The more Uses a spirit has the longer it will live and the more times its power will be used. This is also assuming the spirit has not been healed in between uses. Only the most efficient ability combinations will be shown for each Use level.
