If a unit targeted by Hextech Ray is moved to base with Flash in reaction, does it still take damage or does the spell have no effect?

Ruling: The spell does not fizzle. It resolves with no effect, and the unit does not take damage because it is no longer a legal target at resolution.

Sequence:

• Target legality is checked when the ability is finalized
• Target legality is checked again when the ability resolves
• Abilities always resolve once finalized, even if they resolve to no effect

Nuances:

• There is no fizzling or equivalent mechanic in Riftbound
