Minecraft Dungeons:Arena Battle

An Arena Battle (or ambush for short) is a battle between mobs and players.

Locations
Arena Battles occur in every location in the game. Some locations have boss ambushes, which spawn bosses. Those locations are the, the , the , the , the , the , the and the.

Behavior
Arena Battles behave differently from Boss Fights. First of all, Arena Battles spawn a lot more weaker mobs than one insanely strong mob. Second of all, the battle format differs from boss fights. They usually spawn in waves (like the one in Pumpkin Pastures). The battles usually start out as several weak mobs. Over time, the mobs the waves spawn get stronger until the battle ends, or the boss is spawned. No matter what, battles always spawn mobs that the level that it takes place in spawns. There is one level where the ambush behaves exactly like boss fights (although still classified as an arena battle), the Redstone Mines. There are similarities between Arena Battles and Boss Fights. They are both triggered by certain events like players entering the Arena (like the Redstone Mines battle) or by pressing a trigger (like the bell in the Pumpkin Pastures). Some other triggers include Buttons, Levers and Pillars. There is a chance for these ambushes to have mini bosses, although these mini bosses are treated as Bosses. There are three levels where ambushes spawn two bosses: the Basalt Deltas (DLC), the Crimson Forest (DLC) and the Woodland Mansion (Secret, Ancient). These events have their own special music. So far, it's not possible to have arena battles that spawn three bosses (apart from Ancient Hunts). Another similarity between Arena Battles and Boss Fights is that they can both be started by the Arch-Illager, Jungle Abomination, Wretched Wraith, and Tempest Golem.
