The Errand Doll
STR 3, DEX 10, WIL 13, 5hp. 1d6-2 attack.
Surrounded by a 5ft whistling cloud that it controls. Anyone in the cloud takes 1d6 burning damage each turn, ignoring armour. The doll can see through the cloud. The cloud may not leave the doll's home, typically a single structure.
This tiny doll will issue an errand to any group it encounters. Roll a d6 to see if this task is mundane (6), nearly impossible (1) or somewhere in between. The doll's cloud will follow the group and attack them if they seem to be going off course or not taking the errand seriously.
If they complete the errand the doll will offer its services for any single errand in return. The doll will attempt this regardless of its difficulty.
