Ardande GhostCreature 11

This rarity indicates that a rules element is very difficult to find in the game world. A rare feat, spell, item or the like is available to players only if the GM decides to include it in the game, typically through discovery during play. Creatures with this trait are rare. They typically can't be summoned. The DC of Recall Knowledge checks related to these creatures is increased by 5.

Lost souls that haunt the world as incorporeal undead are called ghosts.

An incorporeal creature or object has no physical form. It can pass through solid objects, including walls. When inside an object, an incorporeal creature can't perceive, attack, or interact with anything outside the object, and if it starts its turn in an object, it is slowed 1 until the end of its turn. A corporeal and an incorporeal creature can pass through one another, but they can't end their movement in each other's space. An incorporeal creature can't attempt Strength-based checks against physical creatures or objects—only against incorporeal ones—unless those objects have the ghost touch property rune. Likewise, a corporeal creature can't attempt Strength-based checks against incorporeal creatures or objects. Incorporeal creatures usually have immunity to effects or conditions that require a physical body, like disease, poison, and precision damage. They usually have resistance against all damage (except force damage, spirit damage, and damage from Strikes with the ghost touch property rune), with double the resistance against non-magical damage.

Effects with this trait can affect creatures with spiritual essence and might deal spirit damage. A creature with this trait is defined by its spiritual essence. Spirit creatures often lack a material form.

Once 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.

Effects 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.

Effects with the wood trait conjure or manipulate wood. Those that manipulate wood have no effect in an area without wood. Creatures with this trait consist primarily of wood or have a connection to magical wood.
