Bal

Bal is a Boss that spawns every 5 minutes in the Khazad-dûm if a player is nearby. Killing the boss allows players to obtain the Topaz Crystal. His health is displayed as ???.

Spawning
The Bal spawns about every 5 minutes in the middle of Khazad-dûm, which can be found anywhere in the lower Y levels of the Crystal Hollows. When the previous Topaz Crystal disappears, the Bal will appear in the center as an expanding Magma Cube.

Drops
Upon being defeated, Bal has a chance to drop items on the ground, similar to how items are dropped from Ender Dragons. Over the duration of a Bal fight, around 25-40 items will drop. These items can be:


 * (rare)
 * (rare)
 * (rare)
 * (rare)

Behaviour
Bal will hop around the arena, summoning Fire Bats and Blazes to attack the player while shooting fireballs. In addition, it will deal contact damage like a normal Magma Cube. These attacks deal low damage, with the Fire Bats and Blazes ignoring the player if they have an Intimidation Talisman or better.

Upon being defeated, it will return to the middle and slowly shrink into nothingness. After that, the Topaz Crystal will appear nearby.

When alive, it makes loud Magma Cube sounds, which can be heard from a medium distance away.

Trivia

 * The Bal is based on the Balrog from J.R.R. Tolkien's Lord of the Rings series.
 * Its spawning place, Khazad-dûm, is also based on the place of the same name.
 * It used to be possible to trap Bal by building a cage around its spawn point, but building in Khazad-dûm is now restricted in order to prevent it.
