This silvery fish is roughly five feet long. Its
purple-striped fins are multi-pointed, and appear to
be very sharp. Thin, almost-transparent threads whip
about it continuously.
Combat
Sebrefins are saltwater fish with amazing
defenses. They use their agility in the water to great
advantage. A sebrefin can whip its threads and fins,
creating a whirl of cuts and slices in its immediate
vicinity.
Thrash (Ex): As a full attack action, a
sebrefin can thrash its body about, endangering all
creatures in its immediate area with its slashing fins.
The sebrefin makes one melee attack at its full base
attack bonus against each opponent within reach,
dealing 1d10 points of damage with a successful
hit.

The serpentine is a long, muscular eel that
preys off of creatures crossing rivers and streams and
wading through shallows. A serpentine is typically
about 15 feet long, with brightly colored scales,
exotic fins, and a slightly draconic face. A serpentine
is best known for its ability to spit a powerful jet
of water at its opponents, knocking them over and
toppling them off of bridges and logs.
Combat
The serpentine lurks near bridges or fords,
waiting for creatures to cross. It is easily spotted,
although most foes ignore its presence, as it appears
unable to get at them. The serpentine initiates
combat by spitting a jet of water at its prey, typically
knocking them into the water. Unless the serpentine
is recognized for what it is ahead of time, this
attack takes place during the surprise round. Once
a victim enters the water, the serpentine swims up
and attacks with its bite. If it fails to knock anyone
into the water, the serpentine flees to avoid ranged

Threads (Ex): A sebrefin continually
whips its razor-sharp threads about. Any
creature within 20 feet of a sebrefin takes 1d12
points of slashing damage from the threads
(Reflex DC 15 halves the damage). The save DC is
Dexterity-based.
Bladed Defense (Ex): Any creature striking a
sebrefin with handheld weapons or natural weapons
takes 1d10 points of piercing and slashing damage
from the sebrefin‘s razor-sharp fins. Note that
weapons with exceptional reach, such as longspears,
do not endanger their users in this way.
Skills: A sebrefin has a +8 racial bonus on any
Swim check to perform some special action or avoid
a hazard. It can always choose to take 10 on a Swim
check, even if distracted or endangered. It can use
the run action while swimming, provided it swims
in a straight line.

attacks. Though it frequently raises its head out of
the water, the serpentine is still a fish, and if pulled
onto dry land is subject to drowning.
Jet (Ex): If at the surface of a pool or lake, a
serpentine can spit a strong and steady jet of water.
For range, treat the jet as a thrown weapon with a
range increment of 20 feet. If the serpentine hits
its target with a ranged touch attack, consider the
attack a bull rush with a +10 bonus on the Strength
check (+4 Strength, +4 size, and a +2 bonus for
charging, which it always gets). The stream always
pushes the target back the full distance allowed,
and it has no speed limit. Creatures pushed past the
edge of a bridge or ledge fall off, although railings
higher than half a creature’s height prevent this.
