Amorphous (Ex)

In its natural form, a phasm is immune to poison, sleep, paralysis, polymorph, and stunning effects. It is not subject to critical hits, sneak attack, or precision damage and cannot be flanked. Also in its natural form, a phasm gains +4 racial bonus to CMB to resist bull rush and grapple attempts and cannot be tripped.

Resilient (Ex)

A phasm has a +4 racial bonus to Fortitude and Reflex saves. (Already included in the stat block).

Editor's Notes

1.  CMB for this creature is one too high; it should be:
CMB +10.
2.  CMD is missing bonuses from the amorphous ability:
CMD 24 (28 vs. grapple and bull rush; cannot be tripped)

GM's are encouraged to use these values.

DC Result

Phasms are aberrant shapeshifters that enjoy impersonating humanoid creatures.


If discovered, a phasm does not hesitate to slay those who know its true nature.


The strange anatomy of a phasm makes it immune to critical hits, sneak attacks, and many mind-affecting spells.


Phasms enjoy novel experiences and items, and will bargain with creatures who can offer them such things.
