Most of them are at lvl 20. Some are at level 25 but It is not necessary. Lvl 20 units are enough here. I don't recommend you replacing Celebration Battler with Micspammer Battler. Instead, replacing Grenade Battler is a better idea. You need a lot of single target firepower to deal with Fat Boy and Exec phase 3. You _can_ replace Celebration Battler still but it may make the game harder rather than easier.
Is butcher battler a viable switch for speed battler? Butcher, despite costing double and moving slower, has more health, anti-black, and gets free rage mode from the fatboys. If not uh pls tell me why
Technically, that counts to but well, Raigforce is dead so you cannot really get it unless you invite a whole load of people to play it. I was banned in Raigforce for skill issue however (Died to Golden Present) so I cannot really get it either way unless I wanna torture myself through the troll obby. When I first got sent to the troll obby. I tried to beat it but then the scream from dying blasted my ears. My ears were fine but I got a headache from it. That's why I didn't keep trying before Raigforce died. I couldn't handle the scream.
