Notes[ | ]
- Obstruct affects
Charge, regular movement, and non-warping Canto effects; warping is unaffected.
- A unit can warp to a space regardless of whether a path that is not blocked by Obstruct exists between the unit and the destination.
- A unit can warp to a space adjacent to a foe with Obstruct active.
- Obstruct only prevents movement through affected spaces.
- Obstruct does not affect foes with a Pass effect or sources of unit movement.
- If Smite could move an ally 2 spaces away, it always does so regardless of whether a foe with Obstruct is adjacent to the space in the middle.
- A unit can attack a foe with Obstruct and then leave the space with Hit and Run, Close Call 4, or a Canto effect.
