Diminisher Grenade I

Grenade

When a diminisher grenade explodes, it twists space-time enough to accelerate the duration of magic and other effects in the blast radius. Any existing effect that has a duration measured in rounds has its remaining duration reduced by 2d4 rounds. If this reduction drops the remaining duration to 0 or less, the effect ends. A diminisher grenade affects only items and spells of the indicated level or lower or, for other effects, only those created by creatures with a CR or level equal to or lower than that listed.
