If you decide to do so your armor is safe with the god of your choice. Everything aside from any potions and your weapon will be RS gold protected by the god you have chosen. Bandos will give you the largest hammer available, Saradomin will grant you an axe, Guthix will give you an axe with spikes (it's put in the weapon's hand, and like the defense cape's emote, it holds a small shield), while Armadyl will provide you with the sword. Each weapon is not superior over the other, and whichever one of these you pick, along with your demon blade (if you have made it yourself) are your only weapons you can use. It is possible to win this battle as long as you pray. Zamorak's magic attack is punching you with both fists of fire. Each fist does 40-60 damage, but can be stopped by the protect from magic prayer. The melee attacks are more common. They include: striking you with his fist, pulling out a sword and cheap OSRS gold striking the victim with it, or tumbling on you, then hitting you with his Hammer. Protect from melee will block these.
