Riftbound Add: what it does
GlossaryAdd is the Riftbound game action of putting resources — Energy or Power — into a player's Rune Pool. "Add [2]" means add 2 Energy; a domain letter (like "Add [Y]") adds Power of that domain instead. Abilities that Add resources resolve immediately once finalized, ahead of anything else outstanding on the chain.
How Adding resources actually resolves
Triggered and activated abilities that Add resources finalize and resolve right away — they don't pass priority the way most effects do, and a spell that Adds resources still lingers on the chain normally once finalized. That immediacy is what makes Add-with-Reaction abilities so flexible: they can be activated the instant costs need paying, even mid-resolution of something else.
Add abilities with Reaction
An activated ability that both Adds resources and carries Reaction can be used at essentially any moment a cost needs to be paid — including during the Pay Costs step of playing an entirely different card. That combination is Riftbound's main way of banking flexible mana on the fly rather than committing it turns in advance. See the Game Actions guide for how Add fits the rest of the resource system.

What does "Add" mean on a Riftbound card?
Add means putting resources — Energy or Power of a specific domain — into your Rune Pool, ready to spend on costs.
Do Add abilities pass priority like other effects?
No — they finalize and resolve immediately, ahead of anything else outstanding, rather than passing priority in the normal way.
Why does Add pair so well with Reaction?
A Reaction ability that Adds resources can be activated the instant a cost needs paying, even mid-resolution of another spell or ability — letting you hold resources back until exactly when they're needed.
