When Leona Determined attacks into a fortified position, does the attacker declare their stun target first or does the defender declare who gets the +2 might first, and in what order do these effects resolve?

Ruling: The attacker's trigger (Leona's stun) is added to the chain first with a target declared, then the defender's trigger (fortified position's +2 might) is added to the chain. Effects resolve in reverse order, so the defender's trigger resolves first, then the attacker's trigger resolves.

Sequence:

• Leona Determined attacks, triggering her ability
• Attacker declares stun target and adds trigger to chain
• Defender's fortified position trigger is added to chain
• Defender's fortified position resolves first (grants +2 might)
• Leona's stun resolves second

Nuances:

• Targets are declared when triggers are added to the chain, not when they resolve
