I love thoses lvl 61 Candle Slug. Evasion recommended and Slugs have accuracy buff. The fight is not has hard as lvl50 but it's going to be long and painful.
Edit: Slug level done. ATK buff over the time and ATK debuff for ennemies is recommended, Counter+Crit was the answer. Once again, Pink Miko saved the game. Nothing can deal with Pink Miko.
Edit: I love how levels 71 to 75 are so easy. RRose+Queen Anemone+Tampala make a good combo here.
Only 5 (or 6? Seems many guys reached lvl 81) level remaning. I don't know why but I'm pretty sure it will be harder than everything in that tower. I pray for no lvl50-like again.
