Steel Caltrops are an easy to make area of effect trap. They can be thrown on the ground and will cover a small area of ground with annoying spikes, which will inflict a 1.4 DPS bleed * and a 30% cripple * to opponents as they walk over them—however, they can be avoided by crouching over them, or destroyed with explosives. If you walk over them, you will have immunity to them for 3 full seconds. Steel Caltrops are very effective for chasing, fleeing, or just simply denying your opponent freedom to move around in one area.
