Quick video showing off how to defeat Draconic Tree Sentinel with no combat required! It's a bit of a known cheese, but I wanted to make a video anyway for those who didn't know. Hope it can help somebody!
STEP BY STEP:
-Sneak around the Sentinel's right side, stay crouched the whole time
-move close enough behind him for poison mist to reach.
-Cast mist, wait for it to run course, then cast again, he should poison on the second poison mist cast.
-Rinse and repeat for about a half hour after poison wears off.
THANKS FOR WATCHING!
