All living targets within the area of effect chosen must succeed at an intelligence save or take 1d4 psychic damage. Each creature that takes damage in this way creates 1 sliver, plus 1 more per 2 damage dealt to them. These slivers will hover near the caster, producing a faint ghostly light. Each sliver can be used to empower other Soulfeeder abilities.   This ability is Incarnum/Psionic in nature, and therefore is not subjected to spells or effects that work on arcane, divine or primordial spells (like counterspell or dispell magic). Metamagic feats however can be used.   Soulfeeder can use 1 of 3 different configurations - 60ft line, 10 ft wide, 40ft cone, 25ft radius centered on caster casting is an action, requires concentration for up to 10 rounds (duration of time the slivers are held on to), losing concentration will result in the loss of slivers obtained at the end of the casters next turn (caster is aware they are about to lose them, and can expend them as a last ditch effort).
