"Your barrier just traps my prey, preventing them from both escaping and retaliating. On top of that, only Abominations need to feed on life force. For the undead, light magic it's nothing but a full course meal!" Scarlett could see the creature's blood cores going into overdrive, lured by the spell's energy mass.
"If you say so." Scarlett snapped her fingers, turning the Source Wall into Night Wall. The creatures slammed into the mass of darkness energy which destroyed their blood cores and made their bodies crumble.
Without the blood core's energy keeping the other two apart, the black core was free to feast on the mana core first and then on the mud puppet holding it in.
