Perp Note, c. 06/16/19: In fairness, I also made it clear that Eowyn was an overwhelming force, so you could probably justify keeping them at Ultima Fire times Two's yield of ~350 Megatons, possibly higher if you'd felt that being in the same tier as Eowyn outright's a bit too much

Starfall is supposed to be a "big" spell, even if Azure can tank her own, it did pretty substantial damage to The Emerald Sentinel.
