For some reason, in D:OS:EE line of sight for ranged attacks is calculated from the character's knees. This is causing small deviations in terrain height to block ranged spells and weapons that travel down a projected path from the caster.
In the original D:OS this didn't seem to be an issue because ranged attacks were fired from the character's chest. I'm not sure if the behavior in D:OS:EE is a bug or if there's some reasoning behind this change.
Thats good to know. Hopefully it wasnt intentional and will be changed.
ty for the info.
