It's easy

Ranti's guides are always so concise and to the point, hmm! By clearly highlighting the core of growth through experience points, this will be a great help to many. Do you perhaps have any more meticulous strategies for high scores, beyond the hidden missions?

I couldn't do it either ㅜㅜ

This is a 1v1 co-op strategy defense game where two players team up to fend off waves of enemies and bosses. Its features include strategic placement and combination of demons (units), tactical upgrades, and a bit of luck. Higher rarity is better.

Thanks. I just played a bunch of rounds and managed to clear it. The hidden one too!!
