From the tree roots extending from the mainland up to the tower, one can find two ladders. One and a foe next to it. It is best to keep anyone within the range of this ladder to prevent falling off. Follow the root up to the outcrop on this tower, as well as the most lower ladder as you climb up. Don't climb the second ladder directly after the first. Instead, make use of Torrent to double leap across the gap in the arched path that is to the right. Climb the ladder at the end of the path instead. Continue left from the at the top of the ladder and continue to follow the path over the top of the building. Double jump Torrent's jump to jump over any gaps, being cautious as there are several that are difficult to spot coming. There's a spot of grace near the end of the path.
