GTNH 2.5.1: The One Ring

The One Ring from Electro-Magic Tools (as of GTNH 2.5.1):

When you put the ring on, you will obtain invisibility and immunity to almost all sources of damage.
While it is worn, the ring has a 1/20th chance per game tick to increase the "mindCorruption" value on your player entity. Note that this is seperate
from warp, but having too high of a corruption with the ring on can lead to warp increasing effects.

You can find your corruption by looking at your player's NBT file (ie using NBTExplorer). The value is under the ForgeData then EMT tabs.

This value seems to reset when you die, or when you leave The End dimension via the usual end portal(!).

Every time your mindCorruption increases, the ring will attempt to roll a few effects BEFORE actually incrementing your mindCorruption.

Effects:
The game will give an ominous warning when you put the ring on without any corruption yet.

The ring will roll for one debuff/non warp effect on the player:
If corruption is atleast 300 and less than 1400, 1/100 chance to inflict Blindness III OR Nausea III for 25 seconds. "The ring feels heavy."
If corruption is atleast 1400 and less than 3800, 1/100 chance to turn off the player's invulnerability and inflict Poison III for 25 seconds.
If corruption is atleast 3800 and less than 6500, 1/100 chance to turn off the player's invulnerability and add 2.0 to the player's vertical velocity.
If corruption is atleast 6500, 1/10000 chance to turn off the player's invulnerability and inflict Wither V for 5 seconds.

The ring  will additionally roll for MULTIPLE warp effects separately:
If corruption is atleast 300,
1/100 chance to increase the warping effect of the ring by 1. This will add an additional tooltip ie "Warping 1". "The ring suddenly starts to glow purple"
1/300 chance to give the player 1 perma warp. "Your body suddenly starts to glow purple"
(Note: This is also supposed to seemingly give 0 to 1 normal warp, but the code didn't take into account that java's nextInt function is upper bound exclusive, and as result this is always 0 normal warp)

Additionally if corruption is atleast 3600,
1/300 chance to inflict 5-9 perma warp, 5-9 normal warp, and 10-49 temp warp. "Your body resonates with the Ring and suddenly starts to glow purple ominously"

Removing the ring:

The ring has a 80% chance per attempt to simply not come off, so simply trying enough times will get it to come off. However, this mechanic seems a bit buggy and it will
probably take quite a few attempts, playing around with the ring, and chat spam to successfully pull it off. The ring will inflict Nausea II for 10 seconds (not additive) on a successful removal roll.
Untested theory: If you lose your invulnerability due to the corruption, taking off and putting back on the ring might temporary fix it.

I guess the way to handle the ring is to not have the ring on for more than 5 minutes to avoid the dangerous warping effects. Note though that since
the corruption increment is random, it is possible to start getting warp effects before the 5 minutes mark. Jumping into the end portal to reset your corruption will
allow extended usage of the ring without inflicting perma warp on yourself or the ring. Regardless, I would recommend having some perma warp removing tool to prevent accidents.
I do not know of any method to remove warp on the ring item, so if the ring warp gets too high to handle you might just have to find a new one.
That was the most I was able to find out about the ring through testing and looking at decompiled code, if there is something wrong here let me know kk thx bye - Fastmapler
