Does Ezreal's Prodigal Explorer ability count each individual target from Repeat spells and multi-target spells as separate 'chosen' instances for the 'chosen enemy units twice' requirement?

Ruling: Each individual target chosen by a spell counts separately toward Ezreal's requirement, regardless of whether they come from Repeat spells, multi-target spells, or even if multiple instances target the same unit.

Sequence:

• Cast a spell that chooses enemy units/gear (like Frigid Touch with Repeat or Bellows Breath hitting 3 units)
• Each separate target chosen counts as one instance
• Once you've chosen enemy units twice total this turn, you can tap Ezreal to draw

Nuances:

• Repeat spells like Frigid Touch count as 2 separate choices even though it's one spell
• Multi-target spells like Bellows Breath (3 targets) or Singularity (2 targets) each count their targets separately
• Choosing the same enemy unit multiple times still counts as multiple separate choices
