Evil Castle 61 to 65F

There are 2 types of enemies here. One is special like Asmode who will not pass turn to you after attack, and other is normal type. If you kill the special type, it will do HP500% fixed damage to all, thus immediately fails. By killing the normal type, it will only do HP70% fixed damage, so you can survive. If necessary get help from healer and kill one normal type at a time. That said the most important objective here is to kill the boss as quickly as you can, because by killing the boss, your units will become invincible like Glacier's buff and all the enemies will explode. Keep it in mind, if the boss is sub-target then you will get damage before becoming invincible.

The easiest way is Beliath + boss finisher + tank, or boss finisher + Lucius. However both require legendary merc, and also for 64F, weak Lucius cannot survive.
