Reverse Cursed Energy
Reverse cursed energy is something rather difficult to obtain. It requires a deep understanding of Cursed energy which is achieved one way or another. However once it is obtained it has to be trained and mastered, it isn't something that is just completely known out of the gate.In order to train your reversed cursed energy you must write 4K characters per session to go up in a Tier. You can only do one training every 4 days. Each tier has its own benefits and limitations
Tier 1
RCE Tier one is basically the starting point and everyone who gains RCT has this unlocked. What you can do at Tier one is heal the injuries of another person or yourself. At this tier you can only heal cuts and scars but not entire limbs.
Tier 2
Tier 2 is where things get a bit more interesting. At tier 2 one has the ability to not necessarily heal limbs but close off the wound to prevent bleeding. In an addition they can fix ruptured blood vessels.
Tier 3
Tier 3 spices things up as the user can now recover limbs but at a slower rate compared to tiers 4 and five. But the user can not heal more complex things such as organs without the use of help.
Tier 4
Almost at the top, you can do it all heal limbs, organs, do the same for other people as well. All of this without the need of help and on top of this you can inject your positive cursed energy into cursed spirits to cause an immense amount of damage to them, bypassing their defenses and possibly even killing them. But there is something missing in all of this as this is not the peak of reverse cursed energy.
Tier 5
This is the highest level of RCT one can gain. At this point the user is pretty much immortal as long as their head is intact and they have the cursed energy needed to heal themselves. On top of this, the user at this stage can use what is known as a "reversal technique" which is the exact opposite of their existing curse technique.
