Strat for Dung Defender where you overcharm with Twister and Shaman. You only need to dreamnail once with this method and you'll have enough soul leftover to use dive right after the fight to get the relic below the arena. Useful for categories that don't care about being overcharmed after this fight with a damage tank.
