Caltrops is a Defensive Demon Hunter skill unlocked at Level 4. The Demon Hunter lays a trap on the ground right at her current location. The trap lays dormant until a monster comes near, at which point it activates, creating an effect (which varies with the runestone) which debuffs any enemy that enters the area of effect.

There is no limit to how many Caltrops you can drop, other than that provided by running out of Discipline. The effect of multiple Caltrops does not stack, so there's no point in casting two that close together, though it can be very useful to spread multiple traps around to increase the area of effect.

The Demon Hunter sets a trap on the ground that goes off when an enemy wanders too close. All nearby enemies are slowed.

The concept of the Demon Hunter using traps and other devices to hinder or attack monsters has been in the game since the very beginning. Caltrops was first seen at the July 2011 Press Event, where it was a level 1 skill. Unfortunately, no information about the skill's function was available at that time.


When the beta started in September 2011, Caltrops was changed to level 2, and then level 3. The skill system was once again overhauled for the Beta Patch 13, and Caltrops was classified as a Defensive skill and moved up to level 4.
