Creating a SoP Energy Wall in a straight line


Using the Spheres of Power rules, the destruction sphere has a talent called Energy Wall

You may spend a spell point to shape your destructive blast into either a wall up to 20 ft. per caster level or a hemisphere with a radius up to 5 ft. per 2 caster levels (minimum: 5 ft). This wall extends up to 20 ft. high and lasts for 1 round per caster level. The wall does not block line of effect, line of sight, projectiles, or thrown objects.

Creatures passing through your wall suffer your destructive blast’s damage and effects as normal. Creatures standing in the wall’s space when it is created are allowed a Reflex save to avoid damage.

I have the following questions:

  • Does the wall have to be created in a straight line (if not using the hemisphere version)?
  • If the wall is a straight line, say down a 5 foot wide corridor, would someone traveling down the corridor take damage each square of movement?
