The lexica botania has no entry for the Ring of Odin in any part of the Lexica Botania this update.

Also just so you know, the Aether 2 mod causes the sojourners sash to no longer step-assist, and causes the ring of Odin to duplicate health when changing dimensions, but these issues are strictly for your knowledge and a problem for the Aether devs.

It is intend that the relic items are without a lexica entry. They have a poem in the tool tip, and that gives you hints as to the effects.
