Ah, that answers one of my questions about the revenant profile. May I make a suggestion about it? Given that the gem appears to be a magical item of some sort, I expected it to offer supernatural abilities to its holder. As such, I propose the following systems:

[hider=Option 1]
Give the numbers more meaning and Oomph.

0: Below average (weak)
1: Average (normal person)
2: Above average (healthy, regular exercise, good genes, the calm one in the family)
3: Uncommon (professional athlete, respected thinker)
4: Unique (Albert Einstein, Michael Phelps, Martin Luther)
5: Super (Spider-Man, Batman, Captain America, Iron Man)
6: Super Duper/Magical (Flash, Thor, Todoroki, Bakugo)
7: Nearly invincible (Superman, All Might, Deadpool)
8: Walking nuke (Goku, Light Yagami)
9: Overpowered (Saitama)
10: Isekai protagonist (Kirito)
[/hider]
[hider=Option 2]
Instead of numbers, abstract it to simplify things.

Stamina: Low/Normal/High
Strength: Weak/Normal/Strong
Dexterity: Slow/Normal/Fast
Intellect: Low/Normal/Smart
Faith: Weak/Normal/Strong
