Minecraft Dungeons:Ghast

The Ghast is a mini boss $$, added in the Flames of the Nether DLC.

Spawning
A Ghast spawns in the Basalt Deltas and the Crimson Forest in Arena Battles where the final wave spawns two. They can also spawn in those same levels, as well as the Nether Fortress in Adventure and Apocalypse difficulty, as a mini-boss.

Behavior
Ghasts attack by shooting large fireballs at the player, which explode and leave behind some fire when they hit a block or player. Just like a lot of other ranged/spellcasting enemies, ghasts retreat when a player is too close.

Trivia

 * The Ghast is one of the only three mobs that can appear as a boss in more than one level. The others are the Illusioner and the Evoker.
 * It's also the only boss that can appear more than once at the same time.
 * The Ghast is seen to have an idle behavior, where if there is no player around, it floats up high and then returns down.
 * In the base game, Ghasts only have a small amount of health (far less then most mobs) whereas the one $$ has an enormous health pool.
 * The Ghast is much smaller than its base game variant, as the one in Minecraft Dungeons takes up a 2x2 space, where as the one in the base game takes up a 4x4 space.
