a discordling taskfiend  

Out of boredom I tried "Annihilated the Unnatural" on these mobs. For some reason, it worked. YES it worked. So to all druids/mages out there with this spell, these are summoned. I also tried turn summoned and it worked too!

So, for some funny reason these ugly beasts are considered summoned.

Also drops Dark Discordling Tongue.

Pulled this mob several times in MPG and every time he was faster than me on bard speed with no drum up. Several times I had to hit him with bard snare, which sometimes stuck, to stay ahead of him on a pull. Couple of times I had to hit Fade Mem in order to get him to back off as I was running to my group.
He casts the normal Discordling spell dot on everybody but it wears off in about 15 seconds after the fight. It almost seems like a dmg sheild thing because it has a 12 second timer but every time it sets to zero it resets with more seconds on it during the fight. I never see him stop to cast so I am not sure how he works that spell.
He has normal amount of HP for this zone and his level, and hits about normal hard for this zone. He does not normally see thru invis.
