Morph Ovum

The Morph Ovum in Heretic is different from the other artifacts. When it is used, several projectiles, which look like eggs, are fired in a spread, similar to that of the Ethereal Crossbow. Monsters that get hit by one of the projectiles will transform into a chicken. At this state, they become very easy for the player to kill.

If the player gets hit by a Morph Ovum projectile, they will transform into a chicken, and will have only 30% of their health. They cannot go over that limit and it's much easier for enemies to kill you. The advantage to this is that the small size allows the player to go through low ceiling areas which could not be reached at normal size.

The effect of the Morph Ovum wears off after a while, returning players and monsters back to normal after a while. Health for the players will be back to 100% additionally.

The Morph Ovum is useless against Iron Liches, Maulotaurs, and D'Sparil.
