Ultra-rare

Ultra-rares are exceedingly rare items that have an exceptionally low chance of dropping, much lower than regular items and Semi-rares. There is no way to make ultra-rares appear more often. In the words of Ryme: "ultrarares aren't affected by anything whatsoever". Specifically, Combat chance modifiers have no effect.

Ultra-rares can either be a rare foe with a guaranteed drop, a rare adventure, a rare drop from a foe, or a rare choice option of an adventure. Once all the requirements for an ultra-rare event have been met, the chance of the event occurring is the same for all ultra-rares, except Filthy sock puppet which has a higher chance.
