How do Trifarian War Camp's +1 Might buff and Thousand-Tailed Watcher's -3 Might debuff interact? Is the +1 Might snapshotted, and what happens when a unit leaves the battlefield after being affected by both effects?

Ruling: Might modifiers are applied symmetrically and continuously, not snapshotted. When a unit is in Trifarian War Camp, it has +1 Might; when affected by Thousand-Tailed Watcher, it gets -3 Might (minimum 1). If the unit leaves the camp, the +1 Might bonus is removed, and the -3 Might effect continues to apply to the new base value.

Sequence:

• Unit enters Trifarian War Camp battlefield: gains +1 Might
• Thousand-Tailed Watcher effect applies: -3 Might (minimum 1 Might total)
• Unit leaves Trifarian War Camp: loses +1 Might bonus, -3 Might effect still applies to resulting value

Nuances:

• Might can be reduced to 0, but units only die when they have positive damage marked on them
• Effects are not retroactively computed; you snapshot effects at the time they're applied and don't recalculate based on previous modifiers that would have applied differently
• The minimum 1 Might restriction from Thousand-Tailed Watcher means a 2M unit at 3M (in camp) goes to 1M, effectively calculating as -2M for future modifications
