Besically what Xninebreaker said... lol and you can try to rank within top 500 in the current even and use that Loreley to replace himiko as your team booster (250% boost instead of 200%.) Yes you'll lose the 15% SR bonus but you'll get 35% more damage from the team buff, plus UR has 29999 max atk/def. It'll allow your booster to survive longer.

If you wanna do extreme dmg, you can even do this: 3x HSR Leviathan, SR Asherah, SR Himiko (Loreley).
