What do we do with this necromancer?

I issued my friends to enter the room, with me following behind. Using my water spell, I made a liquified barrier to obstruct the monsters from entering inside this chamber. Every time a monster attempted to step inside the room, this shield would push them backwards with intense force against the other side.

I could only hope that toss would be enough to kill those bastards once and for all.

Ruby added more heat in the tidal wave, creating an ignition for those who dared to touch the water. Her aid amplified the fire element, making the spell more devastating than it was ever before.

Gooey also poured his toxins inside the water pillar. The violent chemical should amplify the damage if a monster dared to approach the shield.
