PFS StandardWiden Spell [one-action] Feat 1

Druid Manipulate Oracle Oracle Sorcerer Sorcerer Spellshape Witch Wizard 
Source Player Core pg. 128 2.0, Player Core 2 pg. 138

You manipulate the energy of your spell, causing it to spread out and affect a wider area. If the next action you use is to Cast a Spell that has an area of a burst, cone, or line and does not have a duration, increase the area of that spell. Add 5 feet to the radius of a burst that normally has a radius of at least 10 feet (a burst with a smaller radius is not affected). Add 5 feet to the length of a cone or line that is normally 15 feet long or smaller, and add 10 feet to the length of a larger cone or line.

Traits

Manipulate:

You must physically manipulate an item or make gestures to use an action with this trait. Creatures without a suitable appendage can’t perform actions with this trait. Manipulate actions often trigger reactions.

Spellshape:

Actions with the spellshape trait 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.
