If im correct the skull increases your defense stat and it cannot be used. So its like a equip. Because as soon as i got it my defense grew.
Yeah , I saw it under an attack pot which it does more then the hammer but it does appear my defense went up as well
It was a defence pot first but the devs switched it to an attack pot. Best keep a hold of it since no doubt the devs will make an item phase in one of the next ones where you need to use it.
generally, quetzals use their skulls to protect their brains. Food also passes through the skull of the way to the stomach, as the beak is located there. Finally, quetzal skulls make a lovey topping for quetzal necks.
It's like the crystal skulls. Retrieve all 13 and all life's mysteries will be revealed. That being said there's a curse where you and your whole family dies. So way it accordingly.
