I got up to the dragon boss in the crystal cave and I'm stuck trying to chop his tail off.
Stand in front of the crystal and wait for him to charge up an attack. Begin your run behind his tail and he should smash the crystal himself stunning him for a few seconds giving you time to two hand your strongest weapon and go to town on the tip of his largest tail.
Had the most tense fight I've ever had today against Artorias on NG+. I'm usually an almost pure Int build so I only have 16 Dex and 10 Str meaning my melee options were limited. Basically what happened was I ran out of casts when he had about 1/6 of his health left meaning I had to melee him down 39-93 damage at a time and avoiding all of his attacks at all costs. Finally beating him after dodging and attacking once or twice for 5 or so minutes was incredible
