Crystal_haerts
by 47med1112
Crystal_haerts is a Fabric utility mod in which defeating enemies charges a crystal heart that players can later spend on temporary buffs.
What it does
Crystal_haerts adds a crystal heart item that absorbs energy each time a player defeats a mob or another player. The stored energy stays inside the player and grows with every kill, so combat feeds the item over time. Two types of crystal heart are included, and both follow this charge-and-release pattern.
Once activated, the heart spends its banked energy on short-lived buffs meant for risky moments. The effects covered by the author text are slow health regeneration, increased movement speed and reduced damage taken. Players who collect more energy can rely on the heart longer during boss fights, cave runs and night exploration.
The mod runs on the client and on the server, so both sides need it. Files are published for Fabric only, covering game versions 1.21.8 – 1.21.11, with 1.0.0 for 1.21.11 as the latest build on the beta channel. The code is not open source and the mod is released under All rights reserved.
Key features
Energy absorption
The crystal heart absorbs energy from every enemy a player defeats and keeps it stored in the player.
Charging by combat
Each kill increases the stored power, so battle becomes the way the heart grows stronger.
Temporary buffs
Activating the heart consumes stored energy to apply short-term effects during difficult moments.
Two heart types
Two types of crystal heart are available, each handled as a separate item in the progression.
