Line of Effect¶
To target a creature or object with an ability or effect, including making a strike against them, you must have line of effect to that target. If any solid object, such as a wall or pillar, completely blocks the target from you, then you don't have line of effect.
If you're not sure whether you have line of effect to a target, imagine drawing a straight line from any corner of the space you occupy on an encounter map to any corner of a space the target occupies. If one or more corners of your space connect to any corner of the target's space with no obstruction in between, you have line of effect to the target.
At the Director's discretion, flimsy or fragile obstructions such as a glass window or linen curtains don't block line of effect, and might be automatically broken or torn by strikes or other abilities used through them.
If you use an ability that creates an environmental effect, such as a portal, you must have line of effect to the space where you create the environmental effect. If you want to create an area of effect in a specific area, you must have line of effect to at least one of the squares in that area. See Area Abilities above.
