Cursed Wound (Su)

The damage an umibozu deals doesn’t heal naturally and resists magical healing. A character attempting to use magical healing on a creature damaged by an umibozu must succeed on a DC 27 caster level check, or the healing has no effect on the injured creature.

Dooming Gaze (Su)

Paralyzed with fear for 1 round, 60 feet, Will DC 27 negates. A creature that is already paralyzed by this gaze attack and fails a saving throw to resist being paralyzed for 1 more round gains 1 negative level (Fortitude DC 27 to remove after 24 hours). The paralysis effect of this gaze is a mind-affecting fear effect, but the negative level is not. The save DC is Charisma-based.

Draining Strike (Su)

A living creature struck by an umibozu’s slam attack takes 3d6 points of negative energy damage. Alternatively, the umibozu can choose to make the target fatigued for 1 hour or shaken for 1 minute rather than dealing this negative energy damage. If the target is a mythic creature, the umibozu can instead drain one use of its mythic power; it can then use that mythic power itself but must use it before the end of its next turn or it is lost.

An umibozu may expend one use of mythic power as a free action to inflict one negative level on the target (DC 27 to remove). It can expend more than one use of mythic power if it wishes, inflicting one negative level for each use of mythic power it expends. If the hit is a critical hit, it inflicts two negative levels for each use of mythic power it expends.

Elusive (Su)

An umibozu has long been the stuff of maritime legends, but despite countless attempts to hunt them, they are rarely encountered unless they wish it. As a full-round action while in water, the umibozu can move up to its run speed (400 ft.) without leaving any trace of its passing (identical in effect to a pass without trace spell).

The umibozu gains a +40 circumstance bonus to its Stealth check.

In addition, except when in combat, the creature is considered to be under the effects of a nondetection spell. Both of these spell effects are at caster level 20th and cannot be dispelled.

Unholy Grace (Su)

An umibozu adds its Charisma modifier as a profane bonus on all its saving throws (bonus included above).


Environment any oceans
Organization solitary
Treasure standard

Massive and blacker than the darkest depths of the sea, this colossal watery form glares with two immense, hate-filled eyes.

Umibozus are formed from the combined despair and horror of death at sea, such as when a ship sinks and its entire crew drowns. No single restless soul empowers an umibozu—it combines the anger and doom of all who die in such close proximity. Reawakened as vast black masses of haunted seawater and fog, these angry spirits have no memory of their past lives and seek to inflict the doom they suffered on others who ply the seas. Umibozus have an unusual respect for those with wit and guile and sometimes consider sparing those they deem worthy of their esteem. Those who try to defend themselves with brawn and weapons, however, receive no mercy from the enormous monsters.
