Fatal Frenzy

The Killer Tank goes into frenzy mode and charges through the battlefield, dealing DMG to all enemies in its path.

Self-RepairPassive

The Killer Tank takes 50% less DMG while in its normal state. When inflicted with a control effect, it ignores the effect, but one tire is blown. If the control lasts longer than 2s, one additional tire is blown. When all 8 tires are blown, the Killer Tank enters a repair state, disabling its frenzy mode but still allowing it to cast attack skills from its position. During this state, it takes 100% more DMG. Tires self-repair over time. Once fully restored, the Killer Tank will return to frenzy mode. A full repair takes no more than 15s.
