Channel — Riftbound Rules

Section 430 — 8 rules

430.1.: Channeling is the action of taking one or more Runes from the top of a player's Rune Deck and putting them on the board.
430.2.: The Game Effect that instructs a player to channel 1 or more runes may specify the conditions or circumstances under which those runes enter the board. Example: A spell reads "Channel 1 rune exhausted." As that spell resolves, its controller puts the top rune of their rune deck onto the board and that rune enters the board exhausted rather than ready.
430.2.a.: By default, runes are channeled readied.
430.3.: If there aren’t sufficient runes in the Rune Deck, channel as many as possible.
430.4.: Channeling is a Limited Action.
430.4.a.: A player Channels two Runes during the Channel Phase on their turn.
430.4.b.: Players may also Channel runes when Game Effects direct them to do so.
430.5.: This action is formatted as "Channel X rune(s)," optionally followed by conditions or stipulations. e.g., "Channel 1 rune." e.g., "When you play me, channel 1 rune exhausted." e.g., "Channel 2 runes exhausted. If you couldn't channel 2 runes this way, draw 1."
