Notes

Gem of the True Sacrifice: Torn grants you the ability to make the ultimate sacrifice. As a reaction, when a creature you can see takes damage you may choose to take it instead. If this act causes you to fall unconscious, you automatically pass your first death saving throw. Usable once per day.

Gem of the Ultimate Gamble: Torn grants you the ability to convert health into magical energy. As a bonus action, you or an ally who can see the amulet may regain a first-level spell slot. You can try to make this regained spell-slot one level higher by rolling 13 or above on a d20. If you succeed, the spell-slot becomes one level higher. If you roll beneath a 13, you take necrotic damage according to the level of the spell-slot you were trying to convert. This damage ignores resistances and immunities. You may then repeat this process if you choose to do so. Usable once per day.

When used on another creature, any damage you might take from this item is halved.

1st to 2nd: d4
2nd to 3rd: d6
3rd to 4th: d8
4th to 5th: d10
5th to 6th: d12
6th to 7th: d20

Gem of the Martyr: Torn grants you the ability to defend those who cannot. When an ally within 5ft of you is targeted by an attack, as a reaction, you can choose to have the attack target yourself instead. The attacker is then granted advantage. Usable once per short rest.
