For now spell will stop on a tile in front of wall no matter its power. So even paper wall can stop max level magic bolt that do damage similar to .50 BMG ammo. It is stupid, don’t you think?
I just made mod that adds terrain and furniture shatter effect, but because of this limitation i was not able to achieve the main goal - give player the ability to shatter doors and walls if his spells is powerful enough.
Im even ready to code that myself, if the developers will allow me
