Swallow is an attack that drains the HP from one enemy or enemy group. It backfires when used on on bosses. This enemy ability is exclusive to Dahak. There's a glitch associated with Swallow. If Dahak uses Swallow on the entire party, he will heal more then he needs. It has to be group-cast due to the way Swallow is calculated compare to the single target Swallow which the calculation caps the amount of HP gained from it. The bug is on the formula on the group-cast, it will overflow his HP and make it a negative number that instantly defeats Dahak. Unlike normal defeated enemies, Dahak's sprite remains on the screen during the Battle Results.
