Erdtree’s Favor +2

On a corpse in Leyndell, Ashen Capital, available only late in the game after defeating Maliketh, the Black Blade, when coming from the Forbidden Lands. From the Grand Lift of Rold, head west into the capital, go down the stairs and make for the south end of the ash-covered area. The corpse hangs from the top of a tree root sticking out of the ground. Three Ulcerated Tree Spirits guard the area; sticking to the walls as you head south helps you avoid them.
