Basically the goal is to reach all the points without killing anything.

First up is to get next to the box and use high jump to get up to the second floor.


Then go for the spot at the door in the top left.
might take a prep turn or two, you'll want to be near the spot at the beginning of a turn when the cleric is facing away from the door. Use the invisibility ability on the collection spot to both grab what's there and move away from the spot.


From there hop back down and grab the spot on the bottom of the map.
you can sneak past this cleric by using a combination of Invisibility and high jump. The crossbowman won't look in their corner spots.

This needs to be the last spot as it becomes accessible after some cutscene where the box spawns. The moment you end your turn here the mission is over.
