Spirit coraxatrice

A Spirit coraxatrice is a variant of the Spirit cockatrice familiar. Like the Spirit cockatrice, it is a level 43 Summoning familiar whose pouch requirements includes an egg incubated by a Spirit cobra - in this case a Raven egg instead of a chicken egg. Like the Spirit cockatrice, it also has a right-click Drain special ability and can use the Petrifying Gaze scroll - in this case targeting the opponent's Summoning skill instead of his Defence skill. Despite popular belief, the Spirit coraxatrice may also randomly produce Cockatrice eggs, NOT Coraxatrice eggs. This is only Cockatrice variant that doesn't give the corresponding egg.

Petrifying gaze scroll
A Petrifying gaze scroll is created by using a Spirit cockatrice pouch on a summoning obelisk. Doing this grants 10 scrolls. (It is presently not known whether using the Coraxatrice pouch would produce the same scroll. However, this is not recommended due to the rarity of the Raven egg)

Petrifying Gaze
Like the Spirit cockatrice, the Spirit coraxatrice can use the Petrifying Gaze special attack, though with slightly different results: the attack deals up to 100 damage against an opponent and drains their Summoning level by up to 3.

Trivia

 * The prefix "Corax" comes from the scientific name of the Common Raven- Corvus Corax
