Commands
/untouchablecrystal spawn
Creates an "untouchable" End Crystal (immune to damage/explosions, tiny hitbox, doesn't block block-interaction raycasts).
- spawn → spawns it where you're looking (raycast up to 20 blocks)
- spawn → spawns at exact coordinates
- spawn → also controls whether the bedrock base is visible underneath (true/false)
/untouchablecrystal kill
- kill nearest → removes the closest marked crystal to the player
- kill all → removes every marked crystal on the server (across all dimensions)
- kill radius → removes all marked crystals within n blocks of the player
/untouchablecrystal list
Lists all marked crystals with their index, coordinates (color-coded X/Y/Z), dimension, and a clickable [TP] button that runs a direct teleport to that crystal.
/untouchablecrystal tp
- tp nearest → teleports you to the nearest marked crystal
- tp → teleports you to the crystal with that list number
/untouchablecrystal glow
Makes one or more crystals glow (like the Glowing effect/Spectral Arrow), optionally with a scoreboard team color:
glow → glows white for 5 seconds, applied to all crystals
glow → custom duration
glow infinite → glows forever
glow → Minecraft team color (red, blue, aqua, etc., with autocomplete)
glow infinite / glow → color + duration combos
glow index [...] → all of the above variants but applied only to the crystal with that specific index (from /list)
