the 1 cycle you have to position Rabid Rosalina and Luigi where I did because sometimes Luigi doesn't kill so bedrock break the floor and dies any way

if you give Mario rabid revenge upgrade then he will kill the water stooge if you let him get hit in the darkmess puddle in the building with rabid Rosalina I recommend keeping punching frenzy

That's an incredible 1 round! Congrats!

I hadn't thought about the combo of Rabbid Luigi's weaken and Rabbid Rosalina's ennui extra damage skill. Definitely going to have to figure out if I can work that into my run.

(For A Cold Greeting, another method is to get Luigi's Steely Stare damage fully upgraded and he can take out a Sea Stooge as long as he's at a reasonable distance from the spawn point. Though I've had very bad luck with it when recording runs.)
