You should really edit your post

better. now please help me

You can get more humanity from killing rats in the depths, but that is quite the walk just to get more. I think with what you have, you should be able to beat them on your own.

Standing still and hitting with Iron flesh is very hard for this boss. A general tactic for a slower character would be to walk backwards with your shield up and try to get them to separate. When you get one of them alone, wait for a window to attack. Usually immediately after blocking/dodging one of their hits. Just always keep in mind that Ornstein can leap at you from far away, so hide behind pillars to heal, or to get cheap hits in on Smough.

One thing to note is that summoning Solaire increases the HP of the boss, making them take longer to kill. Doing it alone makes tanking a little more viable since you will deal more damage overall to them while taking hits.

One hint I'll give as to the actual boss fight and not where to find materials is:

Sorry if that's too specific. I don't want to ruin the "fun" and like I said, it's still just a pain in the ass fight no matter what.

ok thank u and i lost my other account so this is snuffy i will try to get back in that. but i just need to find a place to get twinkling titanate. thank u and i hear about making something out of quelougs soul that if u make it like +5 its really good for this boss. i dont think i spelled her name right. but thank u for the help. and idk about the walk i want to beat this idc i want past this part before i quit. but then i will make a new one so i wil never stop playing i love this game to much.
