Makeshift Trap

The kobold trapsmith cobbles together a quick trap with materials at hand and throws it at a point on the ground it can see within 30 feet of it. The trapsmith chooses one of the following traps. Each creature in the trap's area must succeed on a DC 13 Dexterity saving throw or suffer the trap's effects.
