The Cracked Mask

Click to reveal..
"One of the heathens has a sack on their head instead of their mask and seems very upset. On a nearby rock lies a wooden mask broken in two. (Name) knows that a simple glue can easily be made from noni sap and sand, but the heathens clearly don't know how to make it. On the other hand, (Name) could fix it poorly to trick the heathen into giving up the mask.
How should (Name) help the heathen?"

Attempt to fix the mask: Heathen doesn't understand at first and injures villager, then realizes motives and is grateful. Villager gains devotion points to trainee level, but now dislikes work.
