No Heal Border

No Heal Border is a server-side Fabric mod that creates a soft world border by disabling all health regeneration outside a configurable area.

Players are still able to travel beyond the border, but any damage taken outside cannot be healed until they return. This discourages very distant base locations without restricting exploration.

The mod blocks all forms of healing outside the border: natural regeneration from food Regeneration effects Instant Health potions absorption hearts (golden apples, effects)

The border is square, invisible in-game, and works per dimension (Overworld, Nether, End).

When a player enters or exits the world border, this is communicated to them through an on-screen title notification.

You can Configure the origin and size of the border for every dimension in the Config file. "\config\softborder_healblock.json"
