Relic notes

I'd slow down or give a cooldown on the regen of the Odin ring. Perhaps you need to go ten seconds without damage before the ring can start healing you?

I would personally remove the fire nullification of the Odin ring. Crimson pendant already does this, and I'd like to be able to wear this and the Aesir ring as a vampire while still taking fire damage.

With the Loki ring effect, perhaps shift clicking on an already "Marked" block removes the mark? I'd hate to need to reset everything if you make one mistake.

Some other effect on the origin mark, as it is impossible to tell the difference between it and others. Forget which one it is, and you are in a huge mess cleaning up marks.
