Cant find it in the malign scorcery or the core rules. But can you move over endless spells? For example can you physically roadblock the the Prismatic Pallisade?
I'd say you can't. The non-damaging ones like the pallisade are physical objects so they're just flat out in the way while something like the burning head would involve walking through, well a giant burning head… which doesn't seem like the brightest of ideas either (get it... bright cuz it's a burning head…)
Haha I get that. I hoped there was some rule on it. In case someonre wants to move overit and treat it like a fence or so.
Endless spells are considered as friendly models for both sides, so no movement over them unless model can fly or has similar rule.
