A big tip on how to get a rough achievement.
Unleash the DOOM! Achievement Guide
This achievement requires you to defeat 3 level 9 opponents on a team against you. A tall order (I think, haven’t played too much yet), but I just found an easy strat for getting it.
- Pick Toph VS 3 Zims, turn friendly fire on and go to the Loud House stage.
- Stand next to the steps and spam your down strong. Rain bridges on those fools as they keep walking right into it.
- If one of them slips by, try and fight them off or run away until you can get them all on the opposite side of the steps again.
- Destroy the Irken scum.
