Next boss after the Sanctuary Guardian is Artorias and his favorite food is players with low HP, low stamina and focus on Sorceries. Makes sure you have a shield with good stability.
I can consistantly get Artorias low but once I run out of soul spears I can't stop his power up. 2h handing my light weapons doesn't do enough damage fast enough unless I'm lucky. Then one mistake and I'm dead....Otherwise magic is doing swell.
If only I had more copies of Homing Crystal Soulmass and Soul Spear, I'd have beaten him already.
I finally beat him by going back to the barnfire and reequipping my normal Homing Soulmass and using it with Homing Crystal Soulmass for damage and Soul Spear and Heavy Soul Arrow to stop his power ups. At the end of the fight I just stabbed him with by BSS about 5 times and he died. I was getting low on health so I was very nervous I was going to die before finsishing him off, yet again. Lucky, he only got 2 failed power up attempt.
Hello 50,000 souls! :D
Thank God I decided it would be a good idea to boost my HP to 1000 HP. Never would have managed to beat this fight without heavy armor (especially high Poise so my spell casting isn't get stopped) and a good chunk of HP.
I also used the Blader Shield since it has the highest base stability out of all the shields I have.
I think I'm going to try to get to 44 int so I can get Crystal Soul Spear. Not sure I'll get it in time for the final boss but I'm not carrying around a bunch of souls here. No way. This will make my final level 78.
