Olympian bracelet

The olympian bracelet is a thunderstone bracelet enchanted by the level 115 spell Enchant Level 8 Jewellery. It doesn't give the player any stat boosts, but instead provides a very powerful boost for when fighting water creature or water spell user. Once worn, you will hit 65% more on water monsters (such as waterfiends). It can also backfire water spells casted by players or monsters, causing at the maximum of 5,000 points of damage.

Since the amulet is untradable, in order to obtain it, players would need to be lucky enough to gain a thunderstone gem through mining(the chances of finding the gem are greatly increased when using a celestial pickaxe, but this requires 110 Mining and is very expensive). Then players would need level 110 Crafting to turn the gem into a thunderstone bracelet, and finally the player would need 115 Magic to enchant the jewelry.
