Activate a Hope Feature
Spells and abilities may also allow (or require) you to spend Hope to activate certain effects. A Hope Feature is any effect that asks you to spend Hope to activate it. If the text instructs you to “spend Hope,” that means you must immediately spend the specified number of Hope, or you can’t trigger the Hope Feature.
When using a Hope Feature, if you already rolled with Hope as the higher Duality Die for that action, you can just spend the Hope from that die instead of erasing a Hope from your character sheet. Otherwise, you’ll need to spend Hope you’ve stored from earlier rolls to activate the effect.
Unless an effect states otherwise, you can’t spend Hope multiple times on the same feature to increase or repeat its effects. For example, if a feature says you can “spend a Hope to add 1d6 to the damage roll”, you can’t spend two Hope and add 2d6 instead.
Tip: Some effects only trigger “on a success with Hope”. This doesn’t mean you can spend Hope on a successful roll with Fear to get the effect; it instead means the effect only takes place when you roll with Hope and you succeed on your action roll. On this kind of effect, you don’t have to spend Hope to activate it—it just happens as long as the conditions of the roll are met.
