| Casting Time | Cost | Duration | | ------------ | ------------------------------------------------------------- | ------------- | | 1 [[Action]] | 1 [[Spelldriving Points\|Spelldriving Point per Spell Level]] | Instantaneous | When you cast a spell while at a [[Spell Cannon]] station on a ship, you can choose to spend a number of [[Spelldriving Points]] up to the level of the [[Spell]] cast (Cantrips count as 1) to cast the spell through a ship’s [[Spell Cannon]]. The spell must have a range of at least 30 feet and it must deal damage. This spell does not use up a normal spell slot for the spelldriver casting the spell. When cast, the spell grants the following benefits: **Damage.** For each [[Spelldriving Points|Spelldriving Point]] spent to cast the [[Spell]], it add an extra damage die to the spell's effect. **Area of Effect.** If the spell targets an area, the spell's area of effect increases by a number of feet equal to 10 time your [[Spellcasting Modifier]] (minimum of 10 feet). **Range.** The range of the [[Spell]] doubles. If a [[Concentration]] [[Spell]] is cast through a [[Spell Cannon]], that canno becomes unavailable to other [[Spelldriving|Spelldrivers]] as long as the spell is still active. Once the spell ends the cannon can be used as normal. > [!EXAMPLE] Example 1 > A [[Wizard]] casts [[Fire Bolt]] through the [[Spell Cannon]], spending 2 [[Spelldriving Points]] (minimum of 1 spelldriving point as a cantrip). The spell’s range doubles from 120 to 240 feet. On a hit, the damage increases by 2d10 for the 2 [[Spelldriving Points]] spent to cast the [[Spell]] for a total of 3d10 points of [[Fire]] damage. > [!EXAMPLE] Example 2 > A [[Wizard]] casts [[Fireball]] through the [[Spell Cannon]], spending 3 [[Spelldriving Points]] (minimum of 3 [[Spelldriving Points]] as a third-level [[Spell]]). The spell’s range increases from 150 to 300 feet. With an [[Intelligence]] of 15, and a [[Spellcasting Modifier]] of +2, the spell’s area of effect increases from a 20-foot-radius sphere to a 40-foot-radius sphere (+10 feet per [[Spellcasting Modifier]]). On a hit, the damage increases by 3d6 for the 3 [[Spelldriving Points]] spent to cast the spell for a total of 11d6 [[Fire]] damage.
