A Bag 'O' Laughs is so worthless I shouldn't even be writing this. It is the weakest material, but synth with a rank a and poof, you have a Golem. It can synth into a Goodybag, and you can build of that.
This is a different writer!!
The Bag O' Laughs maybe rather weak but if trined enough an be powerful. If not it can be synthesised into pretty powerful monsters.
