yeah, you let him play his game and its a bad day. Starting to think a party of only combat casters might turn the tables. 3 cast cantrips to use up the counterspells and the forth drops the hammer and forces the LS.
bonus action cast the branding smite again. Vyrlim has a flash of lying curled up on the floor crying like a little kid, and doesn't quite want to move again.... but does and rushes Vecna.
"You killed Ezzy, you medieval ik-weed!" Yells Vyrlim with a strange feeling of deja vu. "Whoa, deja vu." "Prepare for some most excellent righteous fury dude!" and as an action Vyrlim unleashes his Holy Nimbus over everyone.
Still have V's CS 😌 "You killed Ezzy, you medieval 🔼ik-weed!".... and I'll put Ezzy out of our misery (sorry) and then attack Shadow Yellow, and with a Parn like yell attempt to get to Red & Green.
Vyrlim uses the Lay on Hands ability- 100 hp to Ezzy "Interupt this shade!" I'd move but I dont think I can bypass the symbol I know is lurking somewhere right in front of us.
