Steam Spell
You transform your fire spells into steam, making them more effective underwater. If your next action is to Cast a Spell with the fire trait, you can cast it underwater. When you do so, it takes the form of scalding steam. Underwater creatures do not gain the normal fire resistance for being underwater against this spell, but they don't light things on fire or cause Persistent Fire Damage, nor do they add other effects that would apply to fire but not steam (at the GM's discretion).
Traits
An action with this trait requires a degree of mental concentration and discipline.
Spellshape actions tweak the properties of your spells. You must use a spellshape action directly before casting the spell you want to alter. If you use any action (including free actions and reactions) other than casting a spell directly after, you waste the benefits of the spellshape action. The benefit is also lost if your turn ends before you cast the spell. Any additional effects added by a spellshape action are part of the spell's effect, not of the spellshape action itself.
