Thanks folks!
Mr Teapot,
well, he's a giff...marhsal to warlord is easy, but, giff have 4 racial HD, Large, strength con bonuses in 3.5 and ECL.
so for 4th remove racial HD, give Large Reach 1 (which is more balanced than 3.5 reach), +4 Str, +2 Con, no specials except they can use their head butt as a weapon for 1d6 damage?
Lord no, +4 Str +2 Con is way too good for a 4E race. Use the minotaur PC race stats, either the ones from the back of the MM or the more full-featured ones from Dragon 369, and reflavor accordingly. Change the skill bonuses to something more appropriate and describe Goring Charge as a headbutt, if that's what you want them to be able to do.
