SFS Standard Spellsail [one-action] Feat 17

Source Galactic Ancestries pg. 63
You can ride the waves of energy left in the wake of your spells. If the next action you use is to Cast a Spell that targets a creature within 60 feet, you teleport to an open space adjacent to the spell's target.

Traits

Concentrate:An action with this trait requires a degree of mental concentration and discipline.
Elf:A creature with this trait is a member of the elf ancestry. Elves are mysterious people with rich traditions of magic and scholarship who typically have low-light vision. An ability with this trait can be used or selected only by elves.
Spellshape:Actions with the spellshape trait tweak the properties of your spells. These actions usually come from spellshape feats. 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 Cast a Spell directly after, you waste the benefits of the spellshape action. Any additional effects added by a spellshape action are part of the spell's effect, not of the spellshape action itself.
