If Yi's legend ability gives +2 might to a lone unit, and that unit is targeted by Smoke Screen (reducing might by 4 to minimum 1), then another unit enters play (removing Yi's bonus), what happens to the original unit's might if the second unit is later removed?

Ruling: Yi's legend ability is a continuous passive effect, not a one-time trigger. When a unit becomes alone again after losing the Yi bonus, it immediately regains the +2 might bonus, even if other might modifiers are active.

Sequence:

• 1 might token becomes 3 might (with Yi bonus for being alone)
• Smoke Screen targets it (will apply -4 to minimum 1)
• Paaka Cub enters, token loses Yi bonus and drops to 1 might
• Smoke Screen resolves, applying -4 (but minimum 1 clause only checks on resolution, so stays at 1)
• Paaka Cub dies, token regains Yi bonus and goes to 3 might

Nuances:

• Smoke Screen's "minimum of 1" clause only applies when it resolves; after resolution it's a static -4 modifier that can result in negative might values
• Yi's continuous buff can be treated like Shield, applying as the last thing in the additive sequence for might modifications
• Other continuous buffs (like Orange Lee Sin's assault bonus) work similarly and can also result in negative might when combined with Smoke Screen
