Madstone Rage

The Madstone Rage effect can be caused either by random contact with monsters in the Madstone Crater quest, or by the Madstone Boots raid loot. The duration is 2 minutes, and it provides a +2 morale bonus to strength, a +4 morale bonus to constitution, a +4 Natural Armor bonus to AC, and a 20% speed boost. However, characters cannot cast spells while in this rage, which includes activating spells from items (except potions) as well.
