Demon Eraser is the 3rd stage of The Crazed Tank. Previous stage: Vulcanizer.
Malevolent Eraser has the highest health of any non-collab unit but trades damage for a guaranteed level 2 Surge — Surge-immune units are necessary, and after that the wiki calls the stage trivial.
- A talented Li'l King Dragon deals big damage stacked; Cone Cat and Cat Cactus (Surge-immune, tanky against Aku) are the meatshields.
- The opening LeMurr duo is the hardest wave — single-target but very high DPS; steady meatshielding lets ranged attackers handle them.
- Ramen Cat shuts down the Angelic Gory pushers; Breakerblast interrupts Zir Zeal's burrow; the Haniwanwans are filler (free cash with Esoteric Uril).
This enemy is much more threatening than Manic Eraser Cat. Though it has slightly less range, attacks slower, lacks Base Destroyer and has considerably lower damage, its strong Area Attacks still pack a huge punch.
Zir Zeal revives after dying — without a Zombie Killer it keeps coming back. Bring one to end the loop.
