The effect does NOT stack, but Yes, it can stack with rings that steal health, also I need someone to give me 9 Wolf Blood Sword grass, it takes too long to invade someone as a watchdog of farron for me.
You cant drop covenant items...
You are quite wrong about that. Just from 30 seconds of testing I did in the crucifixion woods on the small crabs, with the right eye ring on and off, I can easily see that having both the ring and the sword equipped gives a larger boost in damage than the sword alone.

AR while two handing the OWCS (w)with and (w/o)without the ring:
0 hits (w)473 (w/o)473
2 hits (w)512 (w/o)497
4 hits (w)574 (w/o)521
Please don't spread misinformation.
Lol claims it don't stack yet doesn't even have the damn weapon.
I do have the weapon NOW, and it is honestly***** because it needs 6 consecutive hits on an enemy. It needs to steal health on kill too, I already have it at +3.
"Lol cmaims it don't stack yet doesn't even have the damn weapon." Dude, have you heard of youtube, and searching up "DS3 Maximum health stolen in a single hit"?
I didn't say it couldn't stack with the pontiff rings, or any other rings.

@Fromsoft, pls buff the Old Wolf Curved sword.
The weapon is quite viable actually, even in pvp. The six consecutive hits to gain hp won't proc all that often unless you're rather aggressive and good at being so but it's still entirely possible to get in pvp, just don't rely on it happening. If you want to rely on constantly gaining HP in combat you should try a regen build instead, plenty of guides on those exist. This sword's main strength is that so long as you land even moderately consistant hits you can maintain a decent self damage buff. This combined with the slight hyper armor and decent range you get with its moveset can make the weapon very powerful when you're used to using it
While 2 handed can it be parried? Got a build idea and 1 more atribute reset. I love this weapon so much but is it worth tradeing in my cathredral great sword?
Only it's R2 can't be parried.
Did you know the charched 2H r2 combos into L2 R2
