Crystal triskelion

The crystal triskellion is a key released on 11 June 2013. The key is divided into three pieces; each piece can be obtained via the following activities:


 * Killing monsters above level 80 Slayer requirement.
 * Getting drops from the rare drop table.
 * Smithing 80% accurate ceremonial swords in the Artisans' Workshop, from mithril and adamant bars.
 * Harvesting a wishing well fruit.
 * Pickpocketing elves and dwarf traders.
 * Chopping elder evil trees.
 * Hunting kingly implings.

The rewards include ores, logs, gems, seeds, ancient effigies and dragonstone armour.

The keys are obtained during high-level (mostly 80+) members' activities. When you find all three pieces, you can combine them into the completed crystal triskelion key. Following this, you use the triskelion's 'locate' function to get directions to the treasure trove.
