Estus
by tsuniko
On Fabric, Estus brings a healing flask modeled on the Dark Souls series, which restores health and refills with charges that a player can use while moving around.
What it does
The flask holds up to 15 charges and can be upgraded with the Potency Flask, which raises its maximum potency up to level 5 and its healing per use. Fabric API must be installed alongside it. Estus is released under the Apache License 2.0 and is open source, with public source code and an issue tracker. The 1.0.0 Fabric file targets 1.21.1 only.
Key features
Refillable healing flask
The Estus Flask stores up to 15 charges and restores health when used, drawing on the stored charges.
Upgradable Potency Flask
The Potency Flask raises the flask's maximum potency up to level 5, so each charge heals more.
Found in world structures
The flask is placed as loot in several structures, including mineshafts, ruined portals and trail ruins.

How it compares
Nether Flask is a Fabric mod for 1.20.1 and is not open source, released under the MIT License, so it does not cover 1.21.1. Elden Flasks targets 1.20.1 and is open source under the MIT License. Soulwarden (RPG Series Plus) covers 1.21 – 1.21.1, also open source under the MIT License, and both sides need it like Estus.
