Drang stops abruptly when Regan yells. The kobold charge freezes him in his tracks. (Hence the low initiative) This is his first encounter! Ever!

The kobold cutting and marking him gets him moving. He opens with a "Gyarg!" and an Invigorating Assault on the kobold who marked him. That will give the Goliath 3 temp hp if it connects.

Spoiler: First attack ever

He will then move five feet in case flanking is of interest to Melhved.
