So here is my first draft of a playable Minotaur for the DnD Next Playtest. Please offer feedback.
Speed: 30 feet
Scent: You have advantage on checks made to notice, spot or search for hidden creatures.
Location Sense: You have advantage on checks made to navigate through mazes, caverns or dense forests.
Minotaur Weapon Training: When you attack with an axe or a hammer with which you are proficient, the damage die for that weapon increases by one steop: from d4 to d6, d6 to d8, d8 to d10, d10 to d12 and d12 to 2d6
Subrace: Choose a subrace. Two subraces are described here: tauren and baphometian minotaur
Ability Score Adjustment: Your starting Wisdom increases by 1.
Connection With Nature: You gain training in Natural Lore or Survival.
Ablilty Score Adjustment: Your starting Strength increases by 1.
Low-Light Vision: If there is no light within 20 feet of you, you treat shadows in that radius as normal light, and you treat darkness in that radius as shadows.
