Does Void Gate give +1 damage to all instances of Icathian Rain or just to instances that target units at the Void Gate?

Ruling: The intended ruling (RAI) is that Void Gate only gives +1 bonus damage to instances that target units at the Void Gate battlefield. However, as written (RAW), if any instance of a multi-target spell like Icathian Rain affects a unit at Void Gate, the entire spell gains bonus damage and all instances deal +1 damage regardless of location.

Sequence:

• Check if the spell affects any unit at Void Gate
• If yes, the spell gains "1 bonus damage"
• Each instance of damage the spell deals is increased by 1 (including instances targeting other locations)

Nuances:

• This RAW interpretation applies to any multi-target spell (like Falling Star) where at least one target is at Void Gate
• The wording has been identified as needing clarification/errata
• The card should read "Spells and abilities deal 1 Bonus Damage to units here" to match the intended behavior
• The terms "affecting" and "bonus damage" are not formally defined in the comprehensive rules
