Revision as of 02:38, October 30, 2016

"A caltrop is composed of four spikes arranged so that when it is tossed on the ground, one spike is always pointing up to slow an advance."


  • Caltrops are small metal spikes placed on the ground and hidden from enemy view. Troops crossing an area filled with caltrops suffer damage and are slowed down. Use caltrops to slow the enemy advance.
  • Hidden trap that damages and slows down soldiers that come near it during it's duration.

Offensive Strategy

  • Avoid them!
  • Keep siege units away from them

Defensive Strategy

  • Close to the keep to slow down the rush
  • Outside the castle to slow attackers down and keep them under fire


  • Duration of caltrops increased from 10s to 60s (Patch 1.11)
