Keywords can be Dependent Keywords — Riftbound Rules

Section 727 — 12 rules

727.1.: A Dependent Keyword is comprised of both a Condition that it is short for, and an ability of some format immediately after the Keyword itself. EXAMPLE: Noxus Hopeful has “[Legion][>] I cost [2] less.” [Legion] is short for the condition “if you have played another card this turn, this card gains [Text],” while “I cost [2] less” is the dependent ability.
727.1.a.: A Dependent Keyword will always be functionally short for a Condition.
727.1.a.1.: This Condition may also have a determined Duration, Time, or Limitation as part of its definition. EXAMPLE: Legion specifies the duration of its condition: “if you have played another card this turn.” This turn is the duration. EXAMPLE: A dependent keyword that is short for “Until you have spent [3] this turn” would include a limitation on its condition. EXAMPLE: A dependent keyword that is short for “After you’ve become an attacker this turn” would include a time after which the condition is active.
727.1.b.: The Dependent Ability associated with the Dependent Keyword is Inactive on the card with the Dependent Keyword until the Condition is met, when it becomes Active
727.1.b.1.: The Dependent Ability is present on the card for the sake of reference or evaluation until the Condition is met See rule 720. Inactive for more information
727.1.b.2.: The Dependent Ability is Active exactly as written while the Condition is true Example: Gustwalker has “[Level3][>] I have +1 [M] and Ganking.” As long as its controller has 3 XP, Gustwalker’s Ganking is active.
727.1.c.: The Dependent Abilities of Dependent Keywords can be of any type
727.1.c.1.: Triggered Abilities of Dependent Keywords must be Active for their trigger to be evaluated.
727.1.c.1.a.: If a Triggered Ability becomes active at the same time as its trigger condition would be fulfilled, it triggers.
727.1.c.2.: Passive Abilities begin applying at the same time the Dependent Keyword becomes true.
727.1.c.3.: Activated Abilities that become Active from Dependent Keywords can be activated at their associated timing after that ability has been granted
727.1.c.3.a.: If the condition for the Dependent Keyword causes the Activated Ability to become Inactive after it has been added to the chain as a Pending Item, that chain item will not be affected and will proceed with being played as normal.
