Any thing worth saving ring of sacrifice for?

[cc\\Nox]

Without spoiling anything, is there anything specific I should save this for (I've got two so far)?

Rare ring of sacrifice can come in useful.

in my opinion regular rings of sacrifice are best used when you died and your bloodstain has alot of souls or humanity that you don't want to lose. If you die again before you recover the bloodstain while wearing a sarcrifice ring, you wont create a new bloodstain, and the old valuable one stays.

P.S. to OP: the 3rd reply contains minor spoilers and the 4th contains major spoilers.

Yes. But if we don't tell you when to use them then it will be to late if you miss your chance keh keh keh

save one for duke's archives, you'll die 1 time there guaranteed

Save one for your first encoutner with Seath. Once you take the elevator up in Duke's archives, that takes you to a room whose walls are covered in crystals, put the ring on.

Any encounters with Seath the Scaleless or when you have a lot of souls you could lose when trying to get back to firelink or a merchant.

[Maude]

First encounter with Seath.

Host says he doesn't want spoilers, naturally you should then tell him exactly when, where and why he needs to put it on.

The community is being too helpful.

^Up while it's true there's literally no way to do that without spoiler because even if he know that he will once need this ring the second he passes the gate it's too late (I know that you can escape but that's not common knowledge for 1st timers) he's dead and he doesn't need ring anymore.
