If Yasuo, Remorseful's might is reduced (e.g., by Ahri's legend effect or Smoke Screen), does that change the damage dealt by his ability when it resolves?

Ruling: Yes, reducing Yasuo, Remorseful's might changes the damage of his ability. Abilities use current information while resolving.

Sequence:

• Yasuo's ability is placed on the chain
• If an effect reduces Yasuo's might (such as Smoke Screen reducing it by 4)
• When the ability resolves, it uses Yasuo's current might value to determine damage dealt
• Example: Smoke Screen would reduce Yasuo's might by 4, making his ability deal 2 damage instead of 6
