The Lich goes straight; if it skips a turn due to fear, it won't have time to attack – only through blinding, i.e., once every 3 turns – killing 1. It requires 80,000 mana just for blinding + 1500 for slowing. This option is clearly too much for the Lich in 1 slot. And the Crystal Golems are destroyed easily.

Then, we spend a little mana on an air elemental and at the end of the battle, when only 1 Lich remains, we resurrect the Ifrit. The air elemental isn't affected by fear, and now we run around with it. The essence remains the same. Elements don't disappear after 99 rounds. Therefore, we win.

There, everything can be finished in approximately 8300 rounds of melee combat.

How? According to my calculations, it takes at least HP*1000 rounds, because the butterfly deals 1 damage.
