As shown, in the form of Werewolf, when casting Albrecht’s Aether Ray, Werewolf’s long arm makes the casting point too far from itself. So when enemies teleport onto you(like what Aleksander and Valdaran would do), or even just walk into you(like what most melee enemies would do), AAR cannot hit them.
Haven’t test but I guess Flames of Ignaffar on Werewolf may behave like this as well.
Actually I’m not sure whether this could really be called a bug. I’m afraid that people might tell me that this is just a deliberately designed action detail. But this has indeed affected the gameplay. Human form and even Wereraven form don’t have such issue.
These casting skills all use such a posture that hands reaching out and skills casted out of hands, and Werewolf has such long arms that it may be hard to fix this without changing the posture. If this would be fixed by changing the posture, I personally have a plan:

Werewolf open its arms wide like this and cast from its chest. XD
Hope this could be somehow fixed.
