This spell counts as a ranged, area of effect of the given form/radius. Pulse form AoEs affect the caster.
Some ranged attacks, typically spells, affect an area. Area of effect attacks that cause damage can only be defended against by evading or blocking and only if the character is aware of the incoming attack.
On a successful Block, the character halves the incoming damage (round up) before resolving the effects. On a successful evade, the character may move a single meter in any direction as normal without provoking any Attacks of Opportunity. If this would carry them outside the range of the area of effect, they are not affected.
Area of effect attacks are resolved against the body.
