This will probably require a guild effort, what i mean by guild effort is everybody sending their best thing to one player, the best would be to be able to fully equip 54 /or 64 ToS / Raleshi (Ditching the H units may be needed.)
So far i have gained 0 Epic item from H dungeons so i doesn't know how bad the rate are (what i mean, is i doesn't know if it's actually even doable)
But if it's doable, then one may get a shot at the orange. I don't think we will ever see it better than orange ... what is the succes rating on orange ? in the one digit % ?
If that damn boss turn orange at 250k it would mean yellow would be at 375k. No moral boost, 54 ToS / Raleshi 3* + 10 ToS / Raleshi 1* are worth 261 070 when fully equiped with epic stuff. So with all the epic, mech and moral boost 375k may be doable but that would be such a pain to get.
Btw ... on 2* and 3* training alone, 54 ToS / Raleshi are 1 890M (1.890.000.000) xD
