Pernix cowl

The Pernix cowl is part of the pernix armour set, obtainable by killing Nex. It requires 80 Defence, 80 Constitution and 80 Ranged to be worn. When worn, it increases a player's maximum lifepoints by 66. This does not increase current lifepoints, only the maximum.

It lasts for 10 hours of combat before degrading, and then may be repaired by Bob in Lumbridge or at a Player-owned-house armour stand. It should be noted that the cowl does not degrade in increments, and its stats stay the same until the 10 hours is up. It is not yet known whether when the cowl is repaired, it can be tradable again - it is confirmed that when the Torva Platebody is repaired it is no longer tradable, so one would assume this same for this Zarosian item.
