When playing Red Darius and then using Challenge or Sky Splitter, does Darius have 7 or 5 might for the spell effect, and does Sky Splitter cost 1 or 3 energy?

Ruling: The spell must resolve first, then Darius will trigger. In both cases, Darius will be 5 might when his ability triggers.

Sequence:

• Play Darius
• Cast Challenge or Sky Splitter
• The spell resolves completely
• Darius's ability triggers after spell resolution
• Darius has 5 might at the time his ability triggers

Nuances:

• For Sky Splitter, the energy cost is determined before Darius's ability triggers, so it would cost based on Darius being 5 might
