Meanwhile, Celo and the mob of elves are rapidly exchanging grievous harm.

The difference is, grievous harm doesn't stick to Celo. And the elves seem obsessed with his genitals. If someone would take a swing at something other than his crotch once in a while, this might be a more even fight. As it is, even when one girl almost severs the offending items with her dagger, he runs her through with a sword he wasn't holding a moment ago as golden light flares from the wound.
