On the eighth day of CRITmas my players got from me,
…eight cubes a gel-ing.
l always thought it would be really entertaining to imagine how goblins would use gelatinous cubes. They can’t be ridden, maybe as things to put in a room if you want it really clean.
Maybe keep them inside small box that gets thrown at attacking forces. A cube bomb.
Maybe trained them to weaken cart wheels and keep a barrier around caravans for long enough that the goblins can get in steal the loots and get out. The cubes run on instinct and conditioning so they know if they leave the goblins alone they will have a huge feast (from the cart and whoever is still on it).
