Pik-chan

Only mythic gears are Celestial Shield, the rest are legendary Chaos Rings and Haste gloves with an Epic Divine Smite. 1* Seiren and 2* Geezer and Mimic. Get any hammer, lance, big potion/vamp, and spiked armor with berserk to clear the first 4 floors and get as much mithril shield to counter the seal enemies, because hammers, lance, and spike rings are useless here because of the seal. Get as much spiked armor and a big potion to connect to 1-3 berserk potion to get to 600+ spikes.
