skill question

Hope im in the right forum,

but is there a skill to remove all stances for a target foe and adjacent? like a shout to remove stances

Nothing that hits ALL adjacent. The closest is a dervish's Irresistible Sweep, which can hit 3 foes with the scythe's natural AoE. All the others are single-target.

Couldn't a Dervish/Warrior using Wild Blow work in the same way too? Seems Wild Blow is just a melee attack, non-specific to a weapon, it can be used with a Scythe. Or is your actual target the only one that gets affected by the attack when you use Wild Blow?

Anyway, yeah, those are pretty much your only options for ending stances on more than a single target. However, if you are just looking to hit through stances and don't want to have to cast/micro Rigor Mortis, Asuran Scan or a stance-ending skill on each and every one, you could use Guided Weapon instead.

Non-scythe attack skills (including bull strike, wild blow, etc.) do not hit multiple targets even if you're using scythe.
Answer to OPs question is: No.

Actually, yes scythes will hit multiple targets with non-scythe attack skills (I just tested it).

Also, Ascan has an anomaly/bug where just casting it on your targeted enemy will allow your AoE attacks to hit all foes through blocking/blind, so long as you keep the scanned enemy targeted.
