Mystic Ambit Incant

The Mystic Ambit Incant is an artifact in Hexen. It is a scroll with a blue rune on it, and activating one has a different effect depending on which class is using it:


 * The Fighter gets a boost of one point to his armor class by adding durability to one of the four armor pieces. Like the Dragonskin Bracers, this is allowed to surpass the maximums for individual armor pieces, capped only by the class's total armor maximum.
 * The Cleric regains a significant portion of his health, if injured. (50 points plus an additional random amount from 0 to 49)
 * The Mage gets more mana. If the player can have any more blue mana, it fills that first, and then gives the remainder in green mana.  (50 points plus an additional random amount from 0 to 49)
 * Pigs get no effect.

The effect will also be applied to all nearby players in co-op, thus it makes sense to gather together when using the Incants to get the most of them. Perhaps because of this multiplayer nature of the item, Incants, at least in the original game's maps, do not appear in single player.

Trivia

 * "Ambit" means a sphere of influence or scope of actions/thoughts/words. This fits well with the multiplayer effect. Latin root: ambitus (circuit). You could roughly translate the item as "magical sphere-of-influence spell".
