Before anything:

For the weapons I basically recomend Royal Greatsword or Troll Greatsword for the main weapon.

The other 5 are free. Just pick any huge and monstruous weapon dropped by bosses like Wing of Astel, Devourer's Scepter, Morgot Cursed Sword, Fallinstar Beastclaw, whatever. Just keep the idea of a demon hunter who uses giant weapons dropped by the bosses.

For the set I'm using Aristrocratic Coat with Leather Gloves and Boots, no Helmet.
