Core Keeper EA | Rings Tier List Maximum Level 

For future tier lists, I recommend taking in consideration the set bonuses

Great tier list! I agree with most of your rankings but the polished octarine ring should be higher B/A tier in my opinion because it has the highest mining speed bonus and if you are using the scarlet drill you will reach 2500 mining damage with a fully optimized mining speed build which make polished octarine rings very desirable for lategame mining builds. The spine ring should also be a lot higher as it's very useful for bosses lategame and most of the time it will help more than a glass bead ring against bosses due to how damage is calculated and the fact that you already have higher damage multipliers compared to boss damage multiplier when eating buff food making the spine rings damage boost larger in comparison to the glass bead rings pure damage boost. Spine ring deserves to be in A tier as it boosts your builds an insane amount against bosses while not doing anything against other enemies making it not deserve an S tier ranking.

Just out of curiosity what would you consider to be your "one ring to rule them all" so far in the game? For your preferred build I mean.

Thanks for all your guides and lists! Do you plan on making an updated version of a mobfarm? :)

I think you should edit it a bit because there's clearly a mistake. You ranked coral ring (62 health and 8% boat speed) at D, but larva ring that only gives 53 health at C rank. That's certainly incorrect. While it's true that larva ring can be gotten earlier, it will also have lower health value than Coral Ring at every stage of its level up. Moreover, at its early levels it's not even high enough to really help. Even two of them don't compare to a single caveling or better enemies attack Even at level 18, their health bonus is just under the max damage from the regular caveling.. At higher levels you would need two of them to eat quarter of an attack. At no point does this ring seem to do you any good. Even the glow ring seems more helpful, since you will at least see the enemies from further away and avoid the attacks in the first place. Well, its set has a use, however. But the ring itself is useless. Later on the same with noble ring, where 28% of healing from health over time is by far superior to extra 3 health.

new version of this? hurts to see the best mage ring at F tier, Glow polish ring its the best now

I know that this has nothing to do with the topic but could you tell me if a slime farm that produces 160 slimes per hour is good? I don't know anything about it...

Not impressed with this analysis. Some items were ranked lower than they deserved because they didn't fit into a general ranged or melee build. For example, you ranked the bone ring as low despite the critical hit chance stat being essential for mage builds.
