Yes, it's the 30% extra damage from the Silver Rapier and the 20% less defense from the Sword of Light that must have done it - obviously the damage would be lower against non-Undead enemies. But that is about the perfect combination of factors! I wonder what the theoretical limit to damage would be...
I observed that the max actual damage my Sprites would do with a Critical was 10 per Sprite (this is including Anga's Ring of course). But that Critical must have been around 18 damage per Lake Fairy, which is phenomenal.
