I think it would be cool to set traps to maybe cause injuries like a bear trap (rough metal) that cause bleeding like caltrops (metal shards) or maybe give you a chance to fall when running like a grease trap (animal fat and wood). The grease trap could be hit with fire and catch on fire to cause damage to anyone who steps on it. Maybe like a poision spike trap so that if hits you then you get sick and puke up all your food.

These traps would make it much easier to kill a bear or maybe you could drop them to stop someone or something from chasing you.
