When Master Yi's Legend passive gives +2 might to a unit with a -4 might modifier (from Smoke Screen), does the unit return to 1 might (minimum) or 0 might when Yi stops giving the bonus between combats?

Ruling: When combat ends and Master Yi stops giving the +2 might bonus, the unit goes to 0 might (base 4 - 4 from Smoke Screen = 0). When combat begins again and Yi's passive triggers, the unit becomes 2 might (4 + 2 - 4 = 2).

Sequence:

• Combat ends, Yi's +2 bonus stops applying
• Unit calculates to 0 might (4 base - 4 from Smoke Screen)
• New combat begins, Yi's +2 bonus applies again
• Unit calculates to 2 might (4 base + 2 from Yi - 4 from Smoke Screen)

Nuances:

• The minimum of 1 might rule does not apply here because Smoke Screen applied its -4 modifier on resolution (snapshotting)
• This interaction falls under the Arithmetic Layer rules
