If Leona (Determined) moves to an occupied battlefield and stuns a unit, can you give her +1 buff from Leona Radiant Dawn before might values are resolved?

Ruling: Yes, Leona Radiant Dawn's buff trigger resolves before the damage step when Leona (Determined) stuns a unit by moving to an occupied battlefield.

Sequence:

• Leona (Determined) moves to occupied battlefield
• Stun triggers
• Leona Radiant Dawn's buff trigger resolves, giving +1
• Damage step occurs with might values resolved
