If you want a VERY easy way the get the achievement to win without moving: Pick Anya on stage 1. Don't move (obviously). pay attention to not kill the shrimps until they are close enough to automatically pick up their XP. Once you get your first level-up, re-roll until you get the researcher's coat, then pick the sleep skill as soon as possible. And that's pretty much it.

Anya has 2 weaknesses, bullets and overconfidence

And that ladies and gentlemen, is why we invest in defense!

one of the best characters for the "no movement" achievement.

About the slow down ability, what you didn't read was VERY important: It says that it reduces your damage for every stack, and the debuff lasts 1 seconds even after moving.

i think it would be interesting if you reacted to hololive's lore or the clips, would be really cool!!!

Um GWolf, it's episode seven in the endslate, not episode one. 😂
