Thorn Bind Hostage is an Enchanter spell with a cast time of 2 seconds and a cooldown period of 15 seconds.


Thorn Bind Hostage causes five shining blue roots[number of roots depends on the skill level] to erupt from the earth and entangle the target. When an ally cuts each of these roots, they cause additional damage.  The amount of damage varies by the skill of the caster, but the maximum is said to be 1,000 damage per thorn cut.  Because this damage occurs at the same time as that inflicted by the ally's own melee attack, it is difficult for an opponent to survive the cumulative damage using HP regeneration powers.[2]

Contrary to popular belief, Thorn Bind Hostage does not actually immobilize the target. Shiroe's Thorn Bind Hostage only does so because of his equipment.
