The Sea Lion: A RM Conversion

Copyright Kerry Drake © 2003

Edited by Nicholas HM Caldwell for The Guild Companion

"They display tremendous courage, always fighting to the death, even against creatures many times their size."

Sporting the head and forepaws of a lion and the body and tail of a fish, a sea lion is a fearsome creature.


Known for their ferocity, sea lions are very territorial beasts. Any creature foolish or bold enough to enter a sea lion territory can expect an encounter with this monster. They have vicious teeth and their paws are huge. Sea lions are more than a match even for most sharks, which they hate above all other creatures. A sea lion's attacks cannot be divided against multiple opponents in the same round. If a sea lion hits with both paw attacks in the same round, it will start to maul its target. Creatures that are mauled cannot attack that round if they have not already done so. It takes a successful Very Hard Strength roll to escape from a maul. When mauling, a sea lion follows up with a bite attack with a +20 bonus to the attack roll, causing double damage if successful. The head of a sea lion, with its thick mane, is treated as AT 3(40), while the rest of its scaly body is AT 4(40).

Difficult to raise in captivity, a sea lion can become a most loyal mount. They are arguably the most powerful potential steeds in the ocean. Their incredible roar can be heard for up to 10 miles underwater, making them very useful as guardians.


Sea lions prefer to dwell in shallow coastal regions. Sea lions eat any type of meat, be it a fish, bird, or even wandering herd animals caught near the water's edge. Sea lions are even able to drag themselves a few dozen yards up a beach in search of meals (Move Rate on Land: 20/Walk/-10). While rare, reports of sea lions hunting near the foreshore creates more fear than a simple shark attack does.

Sea lions travel in packs. The largest of the beasts (usually at maximum level) is the leader. In a sea lion pack the males are superior hunters, which distinguishes them from their land-based cousins.


Sea lions will go to great lengths to hunt down hated sharks. Whether due to taste or some other unknown reason, a sea lion will never eat a shark it has killed, and will leave the carcass for some other scavenger.

Sea lions can remain out of water for up to 24 hours.

A typical sea cat is 12 feet long and weighs 800 pounds.


Sea cats attack on sight, either for food or to defend their territory, and use both claws and teeth to grab and rend their prey. They display tremendous courage, always fighting to the death, even against creatures many times their size. Pairs and prides of sea cats attack in concert, trying to wear the opponent down until one beast can dispatch it.

Hold Breath (Ex): A sea cat can hold its breath for a number of rounds equal to 6 times its Constitution score before it risks drowning.

Rend (Ex): A sea cat that hits with both claw attacks latches onto the opponent's body and tears the flesh. This automatically deals an extra 2d6+6 points of damage.

Skills: A sea cat 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.
