Your suggestions dont solve the problem, because the boss is following me, so I cant craft armor or weapons.
But nevermind, I rather refund...

Really i am at a loss. Obviously let it kill you. then go farm the materials and make what ever you need. then go back to the boss.
i have completed darksouls so bosses like this are trivial to me. Just use your head. it really is not hard
