Monsters with Fire Chains seem to have slightly modified [[AI]] which causes them to move around more restlessly, and makes them more likely to flank, circle, or surround enemies, increasing the chances of the dangerous chains moving over the character.

Patch v1.0.4 in August 2012 reduced the damage of the Fire Chains by 20%.[http://diablo.incgamers.com/blog/comments/official-patch-1-0-4-notes/] That patch also enabled Fire Chains for players, courtesy of some [[legendary]] items that summon a demon that is connected to the player by a Fire Chain that works to hurt monsters.
