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 <showBottom> → 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)
