Minecraft Dungeons:Pillar

Pillars are tall objects that spawn hordes of mobs $$.

Appearance
As its name suggests, a pillar is a small stone pillar. It the ones in Howling Peaks have a few small runes on its sides and one larger one on top; these runes glow blue and purple while the pillar is active. The bottom of the pillar has a few open spaces with gold inside them, which can be attacked and used to eject wind. Pillars are surrounded by a box-shape floor tile which also glows purple and blue while the pillar is active. The ones in the Fiery Forge, Arch Haven, Creepy Crypt and the Highblock Halls look similar, but have a more simplistic design and emit red light.

Spawning
Pillars can be found in the, and the , where a few of them are found per level. They can also generate sometimes in the and the  and a single pillar activated by a lever can be found in the. A pillar with a creeper face can also be found in the, which will only spawn creepers, and a similar one can be found in the that will only spawn icy creepers.

Behavior
When a player gets nearby a pillar, it activates and begins glowing. The pillar then begins spawning mobs in the same fashion as a mob spawner, but the pillar spawns different mobs and does not have a visible health bar. The mobs that a howling peaks pillar can spawn include:

The mobs that can spawn from a Mainland pillar include:

As mobs spawned by the pillar are killed, the pillar begins deactivating and may occasionally eject gusts of wind from itself, which push away nearby entities. After more mobs are killed, the pillar is eventually deactivated. On Multiplayer, the pillar spawns mobs a lot more often. The fiery forge pillars, however, do not do anything other than spawn mobs.

Opening Doors
Howling Peaks Pillars are often used to open doors and gates, where a nearby one is closed after the pillar activates. Once the pillar is deactivated, the door/gate opens again and the player is free to pass.

Tempest Golem
Two pillars appear on each side of the tempest golem's arena, where they play an important role during the boss battle. The pillars are linked to the tempest golem's arms, so deactivating one of the pillars also deactivates one of it's arms. If both are deactivated, the tempest golem will become stunned and vulnerable to attack. The pillars reactivate after the tempest golem's stun period is over, and both of them immediately deactivate when the boss dies. They can also deactivate squall golems but will restore once the pillars are reactivated to support the tempest golem. Each pillar took half the amount of time to deactivate as compare to the rest of the pillars.
