using penetration on rings and harmony crystal on belts u will only get 10 mana regen lol unless u use the lvl 19 cape which decreases Bds main stat "parry". I doubt people will take notice to your guide because u havent mentioned what type of equipment u need , u only mentioned what crystals to use.
Word of advice since axes are useable Bds dont really need to enchant pene anywere.
