if you fight mob where he spawns it nullifies his ability to gate because he's not gonna go anywhere..so just don't pull this mob far from home and you're good and don't have to worry about stuns or mezs..just my 2cp
Just what the subject says. He's immune to stuns, can gate, and will summon. A guess at strategy would be to attempt to mez this mob once its under 20%, or as it is trying to gate if you get if off fast enough. That is also relying on its ability to be mezzed, which I'm not sure of. Will test more to see.
These can be found Left of the first intersection in PoTorment near the other forms of constructs.
