Mournwing

s are level 66 BAMs added to Stronghold of Blood in Essenia in level 70 patch (patch 80 in March 2019). These were named originally Mournmoths, but name was changed in next patch. These are called giant butterflies by some NPCs.

Mournwings are totally new monster design. Last time new open world monsters were added to game in TERA: Fate of Arun at end of 2014. They have special attack that causes you to freeze in place. It works bit like stun, but you can get frozen even while performing a skill.
