Tall Tumor

Tall Tumor is a Core and Rift enemy that punishes mana-reliant cats. At the end of each enemy cat's turn, Tall Tumor drains their mana and deals damage equal to the amount drained, then heals itself for the same amount. It starts at half health, but its vampiric mana drain quickly restores it while simultaneously disabling spell-casting. Cats without mana pools or with mana immunity are immune to the drain effect, making them ideal for these encounters.
