cuz its the very first ring you CAN grab lmao
Just gotta kill the ogre on the hidden path, he drops the ring. (He has an item in front of him, that is a Golden Pine Resin for anyone that doesnt know)

that was the ****ing joke

You should have immediately logged out then logged back in again. You would see the ring as a glowing bit just at the edge of where he fell off. (like a bloodstain where a PC would fall off) This is also how you get the powerful hex chime (and huntsman's copse key) early in the game from the miracle seller atop Heide's tower, when you punch her into the water to drown.

This is perhaps the only ring (along with Ring of Blades) that I will NEVER take off until the game is over. It's that useful.

There is no tree bridge by the ogre that drops the stone ring. Did you mistake the two on the beach for the one to the left of the area before the fire keepers' dwelling?

According to my windows calculator, 30 and 30 combined does in fact equate to 60.

It does indeed apply to multi projectile spells, however I would use a different ring for bosses as they typically have crazy high poise. Better to use something that will give you a bit of extra damage like one of the clutch rings or ring of blades.

Poise doesn't exist tho
