Is spell shaping an option?
The mythras spell shaping rules are amazing and suggest a look over
CTN: 16 | Fatigue: 1 |
Vs: DT | Range: 5' |
Duration: | ---- |
Scaling Option | CTN | Ftg |
Arc Attack (per additional target) | +2 | +1 |
Increase Range (to/per 50') | +4 | +2 |
I'd do
X Arc
CTN: 16 Fatigue: 1
vs. DT Range: 5' Arc (90 Degrees)
Caster is able to focus magical energy to create an Arc Attack within a 90 degree arc in front of the caster. Only one attack (Targeting) roll is made, and the result is applied against all targets within Range.
Scaling Options
Per additional 45 degrees +2 CTN +1 Fatigue
