Mas Effect Updated
by Mest
Players who fight with maces in PvP can use Mas Effect, a Fabric client mod that changes how combat looks on screen.
What it does
Mas Effect focuses on visual feedback during PvP, with most of its effects aimed at mace fights. It adds options to change hitbox opacity and colors, and it draws a trail behind thrown ender pearls. Nothing about the game rules or the server is altered, so the mod only affects what the player sees.
Only the client needs the mod, so a server can run without it. Files exist for 1.21.8 and 1.21.11, with 1.0.0 for 1.21.8 as the latest Fabric build, published on 2026-02-09. The code is licensed as All rights reserved, so it is not open source.
Key features
Hitbox opacity control
Adjust how visible player hitboxes are, which can help track opponents during close fights.
Hitbox colors
Hitboxes can be recolored, making it easier to tell players apart in busy encounters.
Ender pearl trail
Thrown ender pearls leave a visual trail, showing their flight path on screen.
