Begginers dont get discouraged, it only takes 1-2 tries before you can accomplish this feat, nor do you need the best materials, Id say about 20 potions and 20 health stones is sufficient enough... There is also time to rest in between fights.. Dont take on more than you can handle, pull the monsters if need be.
heres my fight video just in case your curious and havent done it yet, sorry the quality is low =/
