Where it happened (which map, which quest, which npc, etc) : Demon Prison District 2
Bug Description :
Any fire skill dmg to Elet monster heals it. Killed them as wiz - pyro - pyro - elem - elem only by autoattacks, Hail and Freezing sphere skills. Fire pillar, Flame ground, Fireball, Prominence and autoattack with enchant fire skill only heals them at full HP with every tick of skill.
That is intended, as you gain as much as 100% additional damage using countering element, some mobs will heal when attacked with elements that support them.
ie: some fire mobs heal on fire attack, water mobs heal on ice attack and so on.
This feature is similar to what we have in RO.
Ehh, that makes grinding for Pyro at 140-165 lvls hard =( Thx for pointing anyway.
Really? Have you tested it yet or just guess? Because fire skills can kill monsters in mage tower normally just damage reduced
Sorry to say that it is only a guess, but please note that element resistant and being the element itself are two different things.
Some mobs can resist fire damage so you deal less damage to them if you use fire attack.
Some mobs themselves are piles of fire or something along the line, you can’t burn fire with fire, but only heal them. Those are what we have in RO.
Unlike a particular game where you can ignite an embodiment of fire, blind a blind monk and silence a mute. 
But they don’t really look like anything close to fire though. They are like “cloak-and-dagger” mobs.
Pretty much they make it absorb. Only know these 2 monsters absorb fire dmg so far (unless it’s not suppose to absorb). Both have fire element.
(Only big slime absorb not small one though.)
Did you notice that Elet can actually also heal you instead of damaging with it’s ground spark attack? Still pretty weird or pretty bugged monster imo.
Huh, didn’t see that. As I recall that skill always did dmg to me.
