The ash skeleton can remain in this ash form indefinitely.

Traits
Something of uncommon rarity requires special training or comes from a particular culture or part of the world. Some character choices give access to uncommon options, and the GM can choose to allow access for anyone. Less is known about uncommon creatures than common creatures. They typically can't be summoned. The DC of Recall Knowledge checks related to these creature is increased by 2.
MindlessA mindless creature has either programmed or rudimentary mental attributes. Most, if not all, of their mental attribute modifiers are –5. They are immune to all mental effects.
SkeletonThis undead is made by animating a dead creature's skeleton with void energy. An ability with this trait can be used or selected only by skeletons.
UndeadOnce living, these creatures were infused after death with void energy and soul-corrupting unholy magic. When reduced to 0 Hit Points, an undead creature is destroyed. Undead creatures are damaged by vitality energy and are healed by void energy, and don't benefit from healing vitality effects.
UnholyEffects with the unholy trait are tied to powerful magical forces of cruelty and sin. They often have stronger effects on holy creatures. Creatures with this trait are strongly devoted to unholy causes, and often have weakness to holy. If a creature with weakness to unholy uses an unholy item or effect, it takes damage from its weakness.
