If Mask of Foresight is removed during combat, does the static bonus (+1 might) disappear?

Ruling: No, the bonus does not disappear when Mask of Foresight is removed. It is a triggered ability, not a passive effect.

Nuances:

• If it were a passive effect, the static bonus would disappear immediately when the item is removed
• Triggered abilities persist for their duration even after the source is removed (like a timed debuff that continues even if the caster dies)
• Passive aura effects would disappear immediately when removed (unlike triggered effects)
