Frost dragons are commonly killed for their 100% drop of frost dragon bones, worth coins each. 85 Dungeoneering is required to access the resource dungeon in which these dragons reside. Using Soul Split, a pack yak familiar with the Winter Storage scroll, (supreme) overload, and high level equipment augmented with the dragon slayer perk, it is possible to get upwards of 310 kills per hour, banking as needed. If using a legendary pet with the ability scavenge (set only to bones) as well as utilising Telekinetic grab to acquire bones from far away and magic notepaper for the bones looted while the special ability bar is recharging one can even kill as many as 360 per hour also resulting in a total of 534,095 combat experience (incl. Constitution).
