Keywords
Area Damage
Area Damage X: A cumulative, triggered ability that means, "Whenever damage from this unit's attack causes a unit in this arena to be discarded, this unit may do X dice of damage to another unit in this arena."
Backfire
Backfire X: A cumulative ability triggered by the initial dice roll that means, "When you roll at least one natural three with this unit's attack dice before re-roll, this unit does X dice of damage to itself when the attack ends." Backfire applies only to dice rolled for an attack, not to dice rolls for abilities like Retaliate.
Precision
Precision: An isolated, static ability that means, "This unit cannot be intercepted." An attacking unit with Precision cannot have the target of its attack changed by a unit with the Intercept ability. "Elude" is the former name of this keyword. Treat any unit with Elude as if it has Precision instead.
Reduced Cost
Reduced Cost X: A selective, static effect that means, "This card’s cost is X if the listed condition is met." Reduced Cost on cards refers to the build cost, except for Battle cards, where it refers to the Force activation cost. For this keyword, the conditional statement will always start with "If" for clarity. The condition must be met in order for you to be able to pay the "Reduced Cost."
