Fish Taur

Combat
Fishtaurs are a pretty straightforward species. With one of the best HP ratings in the game and decent Strength, they make excellent tanks that are capable of receiving a beating while dishing one out in return. They are essentially battleships, amphibious battering rams that are also able to traverse land, albeit slowly.

They have the highest HP of all starter species and the possible Regenerate might make them seem invincible, but their Magic is weak and their lack of Armor means they take all damage as is. If you don't have a healer on hand the damage could stack up surprisingly fast, especially since their high HP makes them vulnerable to Poison. Conversely, a good healer can make the Fishtaur an almost impenetrable wall.

They have Aquatic, Charge move and good Speed, so while in water they can act as offensive tanks. However on any other terrain type, that Speed is crippled, changing their role to a defensive tank for other units to hide behind. Depending on the map terrain, their Dive skill can offset their mobility issues.

Like any other Centaur hybrid, they suffer from the Bad Anatomy trait which makes them vulnerable to being lust-locked. Having another character to relieve them of their lust is recommended, but not essential with a good healer, since they can still fulfil their role as a tank.

Overworld
The Land Mount ability gives them the option to carry smaller party members, reducing the time needed to traverse a land hex, although they're not recommended due to their bad movement on land.

The Water Mount ability gives them the option to carry smaller party members, giving them the ability to traverse deep water and reducing the time needed to pass through water hexes. The fact that they're the only Water Mount available from the start gives them some value.

Breeding
Their above-average virility and below-average fertility make them able to impregnate and being impregnated rather fast and hassle-free.

Moneymaking
Their higher beauty value makes them a better choice for a Brothel spot, compared to a Centaur.

Trivia

 * Their body makes it almost impossible to have normal sex on land.
 * While moving with an erect penis on land, they keep rubbing it on the ground, often leaving a trail of cum whatever they go.
