If Smokescreen reduces a 2 might unit to 1 might (due to the minimum of 1 requirement), and then Discipline is cast to increase might, does the unit become 3 might or does Smokescreen's -4 reapply?

Ruling: One-time might modifications like Smokescreen are snapshotted at resolution. If Smokescreen gives -1 might when it resolves (due to the minimum of 1 might requirement), it will always give -1 might for the duration of the effect, even if the unit's might increases later.

Sequence:

• 2 might unit exists
• Smokescreen resolves, reducing might by 4 but capped at minimum 1, so unit becomes 1 might (effectively -1 from Smokescreen)
• Discipline resolves, adding +2 might
• Unit is now 3 might (1 base + 2 from Discipline - 1 from Smokescreen's snapshotted effect)

Nuances:

• Smokescreen does not retroactively recalculate its effect after it has resolved
• The -4 from Smokescreen is calculated once at the point it resolves based on the minimum of 1 might rule
• Might changes are applied increases first, decreases last
