Limbus

First one I've seen and a 2% drop rate at that!

Huzzah! :3

(Chain Affinity (0%), Sneak Attack, Azure Lore, Cocoon, Protect IV, Tavnazian Taco, Double Minne)

I can't remember if the 50% damage reduction was already in effect when I cast it; I can only remember that the spell brought Omega down to 17%. If Omega has 26,000 HP, 1860/26,000 = 7.1%. 17+7.1 = 24%, which means the 50% damage reduction may have already been in effect. It may have been high variable 17%, so it was closer to 25%, in which case I hit it right before the damage reduction came into effect. Either way, If it was, that would have been a 3700 cannonball normally...

Also, welcome, Drofrehter, to Hephaestus. :3
