Tons of posts of silly druids with their silly lightnings and bug swarms, nothing bout clerics. =)
I found Dyllin just standing there uncamped on Morell-Thule. This is probably cuz this was at 8am. Rooted, nuked with Smite. Took 3 or 4 smites, and a few rounds of melee, so i think the previous post's estimate of 300hp is about right. Maybe a little closer to 350.
Con was blue dubious. Broke root THREE times and resisted once. Best timing as previous post said, was to wait for red smuggler to come down from lookout point, stand beside Dyllin for a bit, then head down towards the water. The fight i had with Dyllin was messy cuz he kept breaking root and interrupting Smite casting. And even then the Red still wasn't back by the time i've looted Dyllin. Blue smuggler was never seen.
Manawise i used about 3 bulbs. Life lost less than one. It is possible to do this quest earlier cuz Dyllin is a wimp, but you'll also run the risk of him breaking your root and running for help.
His exact spawn point is under the tent. RoOt rOoT RoOt, and enjoy.
