When a spell that increases Might is played first, then a spell like Smoke Screen (which decreases Might) is used in response, what is the final Might value? Specifically, does the decrease from Smoke Screen negate the increase, or are they calculated separately?

Ruling: When effects resolve that change a unit's Might, each effect is "snapshotted" when it resolves. The unit's Might is recalculated from its base value by applying all current increases first, then all current decreases. If a decrease would reduce a unit below 1 Might, that decrease is snapshotted to only reduce to 1 Might (the minimum), and subsequent increases are added normally.

Sequence:

• Start with the unit's printed base Might value
• Apply all current increases from resolved effects
• Apply all current decreases from resolved effects
• If a decrease resolves and would reduce Might below 1, it gets snapshotted to only decrease to 1 Might for the rest of the turn
• When the next effect resolves, recalculate from base Might using all currently active increases and decreases

Nuances:

• In the original example (3 Might unit, Smoke Screen resolves first reducing to 1, then Discipline adds +2): Final result is 3 Might (3 base - 2 snapshotted + 2 = 3)
• Snapshotting only applies to non-passive decreases that hit the minimum threshold when they resolve
• If a decrease can apply its full value without hitting the minimum, it does not get snapshotted and continues to apply its full decrease
• The timing of when effects resolve matters significantly for snapshotting behavior
• If decreases ever exceed increases during arithmetic, a unit can be at 0 or negative Might
