Bonus Damage — Riftbound Rules

713.

Bonus Damage is an intrinsic property that can be granted to Deal actions that influence the amount of Damage that the action is distributing.

714.

If more than one instance of Bonus Damage is applied or granted to a Deal action, all instances are summed and applied once.

714.1.

Bonus Damage can only be a positive value, and can only increase the amount of Damage being distributed.

714.2.

If, for any reason, Bonus Damage would be a negative number, then no Bonus Damage is applied to the action.

715.

Bonus Damage applies to the total damage Dealt by one instance of the action.

715.1.

If the Deal action has a single target, the amount of Damage to that target will be increased by the Bonus Damage granted to it.

715.2.

If the Deal action has multiple targets, the amount of Damage dealt to each target is increased by Bonus Damage individually and separately. Example: Singularity is a spell that says “Deal 6 to each of up to two units.” A player plays Singularity while they also control Annie, Fiery, a unit that says “Your spells and abilities deal 1 Bonus Damage.” Singularity deals 1 Bonus Damage to both of its targets, dealing 7 to each.

715.3.

If the Deal action Splits damage, then the Bonus Damage applies to the amount of Damage that will be Split. This can alter the number of targets eligible to be chosen. Example: Volibear, Furious is a unit that says in part “When I attack, deal 5 damage split among any number of enemy units here.” A player attacks with Volibear, Furious while they also control Annie, Fiery, a unit that says “Your spells and abilities deal 1 Bonus Damage.” Volibear, Furious now deals 6 damage split among any number of enemy units at its location, and can choose to split that damage among up to 6 units rather than the usual 5.

Is Ravenborn Tome supposed to be able to grant bonus damage to spells I play on later turns?

No. This is another card that's missing “this turn."

If a spell deals damage to one or more units at Void Gate and one or more units somewhere else, which parts of that deal Bonus Damage?

The Bonus Damage from Void Gate is only for damage being dealt to units at Void Gate. It will receive errata to clarify this. (As a bonus, Bonus Damage will now be fully defined in the rules.)
