Spellshape
Clarifies that a spellshape action's benefit applies only to the very next spell cast, and is wasted by any other action or a delay.

Many spellcasters can gain access to spellshape actions, typically by selecting spellshape feats. 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.
