Winning Caves without boost or insta-troops?

You have to get 100% or you won’t get your reward. At least if the reward is a monster.

Yeah, crap just found that out before checking back here again. Just got 97% and it is for gear. So safe to say you have to be at 100%. So close.

You need to destroy everything inside dungeons i. e. - you have to get 100% to proceed further. 

If you got 97% keep it up, you’re almost there  :grinning: .

1 Spell or Unit Upgrade should also do the trick
