After the previous chapter, we’ll have to sail over to Pinos Isle. When you arrive, you’ll find Opia at the assassin icon in the shallows at the very southwest corner of the map. Speak with her to begin the next mission.
As we begin, we’ll need to tail the guard ahead down the beach a short way and then up the dirt path to the left that climbs the nearby hill past one set of ruins before entering a second ruin area.
There is no shortage of stalking zone shrubs along the path that he takes you through, so you should have no trouble staying behind him and out of sight. He will stop three times, but as long as you keep to the bushes, he won’t have a clue that you are there.
When he enters the second set of ruins, your objectives will update and you’ll be permitted to kill him as well as the group of four guards on the lower section of the temple below. There are several powder kegs and barrels around the location of the guard group, so feel free to shoot those first to thin out the numbers before attacking.
Once the marked guards have all been killed, quickly hide in a shrub nearby if you are able (if not, it’s all good but perhaps a little more difficult). A second group of enemies will rush down to attack you from the stairs to the northeast. Again, shoot the barrels along the path if there are some left to drop a few of the bad guys before they can reach you. Kill off any survivors.
After dispatching the second group, our target will appear nearby indicated with a red objective marker. Quickly chase her down and shoot/assassinate her to complete the mission and Opia’s Templar hunt side-mission.
