Ghost of Tsushima's Iki Island expansion offers a new side-activity centered around freeing captured monkeys from the Mongols and then playing a flute mini-game. Below, we've compiled a guide on how to find them all.

Completing one Monkey Sanctuary earns you the Charm of Mashira's Protection. This defense charm extends the window of your Perfect Parry and Perfect Dodge maneuvers upon healing yourself with Resolve, and completing subsequent Monkey Sanctuaries increases that window even more. However, when the charm is equipped, it's worth noting that all healing costs one additional Resolve point.
