I might not of focused enough on Strength / Dexterity at this point? (can't wield the heavier weapons / greatshields) but this is my first ever souls play through so I'll have more knowledge on the next run.
My Pyromancy flame is the max ascended +5 form and my best weapon is a Lightning Gargoyle Halberd +5
I actually had less trouble with Ornstein & Smough (beat them solo) my main problem with Knight Artorias is his speed vs. mine, When I cast spells he does a ton of damage to me in the process of casting, and my Halberd is only taking small bites from his health.
A few general things:
- You should really consider having combustion and greater combustion (you have the slots for it, just take the tempests out).
- Knight shield is bad, low stability, heavy, no nice bonus. Consider the Grass crest shield for stamina regen, which you need because you have full Havel's, or the Balder shield for a light solution with great stability.
- The Red Tearstone ring doens't help you at all. Swap it for the Clorantine ring of the FaP one.
Regarding Artorias:
- You can block most of his attacks. Dodge when he jumps or does the running stab.
- After his attacks he stays wide open for 2-3 seconds. Hit him then (1 hit for sure, 2 if you feel safe).
- Every 25% missing HP he will roll away and power-up. Interrupt it at all cost (2 hand your weapon and whack him, twice is enough)
