Tome of Power

The Tyketto's Tome of Power is an artifact that appears in Heretic and Hexen II. It looks like a black book with a skull on the cover. Activating the Tome of Power temporarily gives all of the weapons their power mode. The Tome of Power can also restore players to their normal state if they have been transformed into a chicken by the Morph Ovum.

Strategies

 * The Tome of Power and Gauntlets of the Necromancer make a powerful combination. A player being healed by powered-up gauntlets will rarely be killed unless surrounded by enemies.

Power Modes of Heretic Weapons

 * Staff - Becomes surrounded by blue energy that gives it increased power.
 * Gauntlets of the Necromancer - Their aura becomes red, and they drain health from the enemies that they damage, healing the player.
 * Elven Wand - Fires in a spread pattern, similar to Doom's shotgun, but with the addition of a pair of slower fireballs with each shot.
 * Ethereal Crossbow - The number of bolts fired with each shot increases to five, and the bolts are more powerful.
 * Dragon Claw - Slows down in firing rate, but each shot splits into a ring of spiked balls that tear through enemies.
 * Hellstaff - Slows down in firing rate, but causes a fiery substance to rain down over the area each bolt hits. The bolts can also home in on an enemy if one is in the line of fire.
 * Phoenix Rod - Acts like a flamethrower, unleashing a torrent of fireballs that deal heavy damage, but have limited range. Holding down the button has the best effect; however, each ammo unit used will burn out after 10+ seconds of continuous use.
 * Firemace - Fires huge steel balls that bounce around and deal severe damage, and will automatically kill any non-boss enemies with a single hit. They will also bounce in a seeking form, thus if a targeted monster dodges the first shot, it will bounce back at them from behind.
