Arachnomares are eight legged, hooved beasts created by some demented drow in an effort to combine the “best” aspects of a warhorse and a giant spider.
They tend to be red-brown to solid black in color, with a horselike head (aside from spiderlike mouthparts) a slightly divided body, and eight razor sharp hooves. They climb walls, spin webs (although not in combat) and are quite poisonous and notoriously vicious. They are intelligent for beasts of burden, but absurdly ill tempered and sadistic. Once they “bond” with a rider/handler; a long and dangerous process, they will fight to the death to defend them, and accept no other riders.
They use a blend of the stats of a Warhorse and a Blade Spider. Mostly the latter.
