Limbus Company || The 4th Walpurgisnacht Hard mode all quest Solo Solemn Lament Yi Sang

needed 2 runs to finish this one cause of the 6 Status effect one, probably can do it in one too

To note :
1. Need to get lucky turn 1 so you don't stagger, to make it easy for the first turn, pick your target carefully, prioritize using Skill 3 on enemies that are using 2 skills, or are using 2 coin skills
2. For the AoE Ego (4 Match Flame, Corroded Sunshower), make sure that the AoE targets the body so it also gets the debuff
3. When not doing the 6 debuff quest, can borrow Solemn Lament Yi Sang with Bygone Days equipped so he's not Envy fatal
4. Using any ego before the last wave might make you lack on Ego Resources for the last one

Corroded Sunshower has 2 debuffs (Sloth and Pierce Fragile)
4 MF for Burn
UT4 Crow's Eye View for 2 ATK power down
Yi Sang's own skill inflict Sinking and Butterfly
