Thanee said:I would say no, it only allows you to move even if affected by magic, that specifically impedes movement (like Entangle, Slow or Web). I wouldn't see Telekinesis or being grappled by a Evard's Black Tentacles as such, altho, if you are inside the area of a Evard's Black Tentacles, you could move at full speed (unless grappled, that is). While you are unable to move, that is not a spell that impedes movement. The lack of movability is just an indirect result of the effect of the spell, not the direct effect itself, basically.
Whether it is a direct result of the effect of the spell or an indirect one (which btw, direct vs. non-direct effects are not that well defined anyway) is irrelevant.
If the spell impedes movement (regardless of how), the ability ignores it. Entangles, grapples, it does not matter.
Now, a wall spell does not impede movement, nor does it affect the character (i.e. the character is not a target of the spell effect). The character can move all they want, they just cannot move in a specific direction that they want.
But any spell effect that grapples and directly affects (i.e. targets either directly or within an area of effect) the character impedes movement by definition. The character cannot move and the reason he cannot move is the spell, hence, the ability works.
I agree, however, that the ability does not protect from a creature grappling the character, including a summoned creature.
