Well, I haven't done up a character class in entirely too long, so a quick and dirty writeup of that labyrinth denizen and antagonist of disoriented heroes everywhere: The Minotaur!
(Made up for OSE-B/X, or similar old-school flavored games)
Saves: As dwarf
Allowed armor: Light or medium, shields
Allowed Weapons: Single or two-handed melee
Requisites: STR, CON 12
Prime Attribute: STR/CON
A denizen of the labyrinths and dark, twisting places, your chimeric, monstrous appearance keeps you on the edge of the civilized world.
Unless, perhaps, some serious muscle is needed, a spectacle is demanded for the gladiator ring, or a party needs someone who does not get turned about in the underground. And then, who do they call? Your bull-headed self of course... Hulking and outcast, you tend to be a loner, but will join up if the coin is good and the maze is worthy of your nose for direction.
Your native habitat is the mazes and winding passages, either engineered or natural. You have an inherent sense of direction underground, and can readily track back to the last known exit or passage to a level change.
You’re a big boy (or girl). Your height is six feet+1d12 inches (watch your head). Armor costs 25% more to fit your majestic physique. That bullishness, though, has made you tough as nails. Add your CON bonus to your armor class.
You much prefer to get up close and personal for bashing, stabbing, and slashing, so missile weapons are not on your shopping list. That said, you can use two-handed weapons single-handedly.
That whole man-eating thing is a myth... Isn't it? Whatever. You can forgo your weapon attack to bite or gore (1d6 damage) an opponent.
You may be big, but you're surprisingly light on your feet. You may move silently in the tunnels as a thief of the next higher level.
And, of course, you can see in the dark (infravision to 60'). Not much good underground otherwise, eh?
