What does the Chalice of Blood do?

I want to know what does the Chalice of Blood do? And is it worth it?

Note: I am not playing vanilla Pixel Dungeon, but with the mod "Deistic Pixel Dungeon"

It increases your health regeneration. This is definitely worth it if you can survive powering it up.

The Chalice of Blood was introduced in the Shattered Pixel Dungeon mod. Per the wiki:

Abilities:
Passively increases health regeneration by reducing your regeneration delay, as long as you are not starving. The default regeneration delay is 10 turns. The Chalice decreases regen delay by (level * 0.9). At +10, the Chalice reduces delay by 9, resulting in a restore rate of 1 HP/turn.

Upgrading:
The Chalice is upgraded by using the 'prick' command, which deals damage to the Hero/ine in exchange for an upgrade. This damage is a danger in the short term, but the increase in regen is very helpful in the long term. You don't have to upgrade all at once; wait until you're strong enough to take the damage.

Just to confirm that Deistic Pixel Dungeon did not change this, in the last update for the mod (0.1.5), before it went on hiatus, I found the github repo.

Based on the ChaliceOfBlood.java does not seem to be any different than the same file in the Shattered Pixel Dungeon repo.
