So - apparently - Necros cant hurt a cow. Not even with AOE because they are required to adequately target monsters and critters.
If a Necro is moving and or impeded while trying to cast: the cast will go off screen.
It seems bosses are large enough to anchor curses… Which is odd, but normal monsters and critters will not impeded an off screen cast… Even if the target is the only visible on the map AND directly positioned along the path of the cast (of hemorrhage for example).
Now here is the messed up thing: it affects AoE casts like Reap and Blood Surge.
There is no logical scenario as to why reap would miss a target in range or why blood surge should miss either.
Thus: plz fix or add a target reticle
