【Limbus Company】7-34 (4 Turn Kill) 4ターン攻略 破裂 

You can get 5-6 turn kill with solo Lantern Don Quixote.

The fight is generally much easier with rupture. Seven duo, Seven Outis, FangHunt, Lantern and Warp Yi Sang. Stack up count, cash in on it, ignore her supports and chip damage. Melts within seconds without backup on a half underlevelled team (lvl 50 on Seven duo and FangHunt are recommended)

Ring Yi Sang's Rupture application isn't consistent on average. It's even more RNG when you already need RNG for Talisman Sinclair's skill order.

Because he is shit in rupture
