This skill allows you to increase the affected area of your rune cannon blast and can be used with any rune cannon skill.
For every 2 Soul you spend on this skill, you can increase the affected area by 1 step. The initial 2 Soul changes the affected area from a single target to a single space. Each additional 2 Soul spent increases the affected area by 1 space. The affected spaces must surround the initial target. You cannot create a straight line of affected spaces; instead, the blast forms a ring of affected spaces around and including the initial target. Anyone within the affected area is affected by the blast.
The maximum area increase is limited by your Arcana trait score. Each step (2 Soul spent) of the increase counts toward this limit, including the initial step that changes the affected area from a single target to a single space. For example, if you have an Arcana score of 3, you can increase the affected area by a maximum of 3 steps. If you have sufficient Arcana and Soul, you can create multiple rings of affected spaces around the initial target.
If you fail this skill, any other connected skills that succeed can still be used, but the blast does not gain the increased area. The declared Soul cost for Power Blast is still spent.
