Most of the Leader's in 4th edition have a close burst 5 Healing power.
If the target of the Healing power is completely blocked by a wall from the Leader, can the Leader still heal the target?
If the Leader has neither line-of-sight or line-of-effect can she still heal a target?
No,
Bursts DDI do not go through walls. Because:
A burst affects a target only if there is line of effect from the burst’s origin square to the target.
A line of effect DDI is
A clear line from one point to another point in an encounter that doesn’t pass through or touch blocking terrain.
Walls are the first example given for Blocking Terrain DDI.
No,
bursts (and blasts and walls) require line of effect (that is blocked by walls) from their origin square. They don't require line of sight.
