Didn't see this posted, anyway it's fairly simple but fun
If you go to CoT-Stratholme you will change into a human but if you shapeshift you will go to the appropriate animal form. Now if you eat a savory deviate delight and then shapeshift you lose the pirate/ninja costume but will still have the human buff, thus allowing you to stay humanoid. Not sure if this was introduced with 3.1 because I'm pretty sure I've tried this before with no succes.
Confused my party atleast!
