Strategy
Tamamo no Mae behaves the same as her hopeless battle in the main story does, except this time you need to win. Be warned that she now reflects ALL magic attacks back, so you cannot use Taoist Skills to weaken her. Compared to other super bosses, Tamamo no Mae is simple, she only has one attack that hits more than once, with the rest being pure damage except Lord's Mystic Eyes, which can be mana drained away. She doesn't do any fancy attacks, and if your team absorbs earth, that's another move that can be safely ignored. Since all of her moves have cooldowns, you can take a guess on what move she will use next, gambling on right after her 6 hit random attack is used, to build up a strong combo to OHKO her.
