Kind
General trait
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 (see Oracular Curse on page 132), and the effects of any cursebound ability end when you Refocus and remove the cursebound condition.
General
Cursebound is one of 112 general.
