Description
⚠️ Withersilla cannot be killed. Do not attempt to fight it in survival without creative mode or a way to escape its 64-block range.
Withersilla is a colossal boss mob standing approximately 30 blocks tall. It resembles a massive, blue-tinted Wither and is completely immovable — once summoned, it roots itself to its spawn location and never leaves. It does not naturally spawn anywhere in the world and can only be introduced via its spawn egg.
Its sole purpose is destruction. Every second, Withersilla calls down lightning bolts on up to five living creatures nearby, making it an engine of perpetual devastation for any area you choose to unleash it on.
| Content | Description |
|---|---|
| Withersilla (mob) | A colossal, invincible, stationary boss that continuously strikes nearby entities with lightning. |
| Withersilla Spawn Egg | The only way to summon Withersilla. Found in the Spawn Eggs creative tab. |
Every second (20 game ticks), Withersilla targets up to 5 living entities within a 64-block radius and strikes each one with a lightning bolt. Each strike also deals 100 points of direct damage on top of the lightning's own damage, making survival in its vicinity nearly impossible.
Withersilla cannot take damage from any source — weapons, explosions, potions, void, fire, or anything else. It has no weakness and cannot be killed.
Withersilla is permanently anchored to the exact spot where it was spawned. It cannot fly away, be knocked back, or be moved more than a few blocks from its origin point. It also has no gravity, floating in place at the height it was summoned.
Withersilla never despawns. Once summoned, it remains active in the world indefinitely until the chunk is unloaded or the entity is removed via commands (e.g., /kill).
Withersilla awards 500 experience points when it dies — though under normal circumstances this is unreachable without commands.
Summoning safely: Always summon Withersilla from a distance in creative mode, or ensure you have a fast escape route. The lightning begins immediately upon spawning.
Using it as a trap: Because Withersilla stays in one place permanently, it can function as a stationary area-denial hazard. Lure enemies into its radius to watch them be annihilated.
Removing Withersilla: Since it is invulnerable to all damage, the only reliable way to remove it is the /kill command or a command that targets its entity type. Use /kill @e[type=withersilla-xcu4qkjw:withersilla_xcu4qkjw] to despawn all active Withersillas.
Safe observation distance: Stay beyond 64 blocks from Withersilla to avoid its lightning targeting entirely. Its shadow and scale make it visible from far greater distances, so you can observe safely from a high vantage point well outside its strike radius.
