Blood-magic-combat-buffs
by gamingartis1
Blood-magic-combat-buffs lets players sacrifice their own hearts to gain temporary combat buffs chosen from a menu of ten effects.
What it does
Players open the buff menu with the B key in game and pick from ten combat effects. Each effect trades hearts for a stronger fight: damage can be amplified, speed enhanced, armor reinforced, or attacks given poison, and some effects add damage absorption. Each buff comes with a cost, since the hearts spent do not regenerate until ten minutes after the effect expires. A cooldown timer is shown for every effect, which keeps the buffs from being used constantly.
The mod is built for PvP servers and survival multiplayer, where choosing a buff is part of the fight. It runs on the client and the server, so both need it. Installation needs Fabric Loader 0.19.3 or newer and Fabric API 0.152.2+26.2, and the mod is published for Fabric only, with 0.1.0 for 26.2 as the sole file. The project is open source under the Mozilla Public License 2.0, and its source code, issue tracker and wiki are public.
Key features
Ten combat effects
The menu offers ten distinct buffs, from damage and speed to armor and poison, so players can match a buff to their approach.
Heart sacrifice cost
Each buff is paid for with the player's own hearts, which makes the choice a trade between power and survivability.
Regeneration delay
Spent hearts stay gone for ten minutes after the effect ends, so repeated use has a lasting cost.
Cooldown timers
Every effect shows a cooldown timer, which limits how often a player can activate a buff.
Press B menu
The buff menu opens with the B key, so players can switch buffs without leaving the game.
