Mystery Conduit Feat 20

Anything that doesn't list another rarity trait (uncommon, rare, or unique) automatically has the common trait. This rarity indicates that an ability, item, or spell is available to all players who meet the prerequisites for it. A creature of this rarity is generally known and can be summoned with the appropriate summon spell.

Abilities with this trait tighten your oracular curse's grasp on your soul in exchange for divine insights, giving you the cursebound condition (see below). When you use a cursebound ability, you become cursebound 1, or if you were already cursebound, you increase the value of your cursebound condition by 1. As cursebound abilities are directly linked to your oracular curse, you can't use a cursebound ability if you don't have an oracular curse or if you are already at your maximum cursebound value. You can't mitigate or bypass the drawbacks of any cursebound ability with spells or other effects, and the effects of any cursebound ability end when you Refocus and remove the cursebound condition. A cursebound ability that allows a defense uses your spell attack modifier or spell DC unless noted otherwise.

This indicates abilities from the oracle class.

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.
