DropBar turns your XP bar into a threat radar, focused entirely on what actually wants you dead. Coloured pips track nearby hostile mobs and angry “neutrals”, mapped to the XP bar from left to right based on direction, with size and fade hinting at distance and danger.

Pips dim when mobs hide behind walls, and flare with a RED glow when something is actively targeting you, glanceable awareness baked into UI you already read.

Normal mode uses a rich colour language for mob families (creepers, skeletons, nether brutes, fliers, bosses and more), while A11y mode swaps to a high-contrast palette that’s easier to read under stress or low vision.

DropBar is client-only and lightweight; it works in survival and adventure without any server installation or configuration. Just drop it into your Fabric 1.21.10 instance, press O in-game to cycle Normal → A11y → Off.

Perfect for hardcore worlds, challenge runs, new players and everyday cautious caving sessions.
