Vital Edge

Vital Edge renders a subtle 4-edge screen gradient that reflects your armor's durability — no HUD text, no icons, no new items. Just ambient color at the edges of your screen.

How it works

The overlay color shifts based on your equipped armor's aggregate durability:

Durability	Color
70–100%	Green
40–69%	Amber
15–39%	Orange
5–14%	Red
<5%	Pulsing red (shore wave)

No armor equipped → overlay off entirely
Partial armor → calculated from equipped slots only
Damage surge → heartbeat pulse on taking damage
Biome blend → subtle hue shift based on your current biome
Y-height modifier → brightens above Y=0, darkens below

Configuration (Mod Menu)

Setting	Description
Overlay	Toggle on/off
