More Challenging Trial Chamber

 By using another Trial Key, you can spawn random enemy waves, similar to a village Raid. To make the challenge harder, both players and mobs within a radius of spawners gain the "Corrosion" effect, but with different outcomes: mobs are slightly buff (HP, speed, damage, ...) while players cannot place or destroy blocks (further negative effects, such as slowness or blindness, might be frustrating instead of fun). 

 In addition, here are some suggestions for other chamber room types:

- Submerge: This room follows the ocean genre, filled with water, with magma bubble columns and sea plants. Enemy spawns here are aquatic hostile mobs, with Elder Guardian as the final boss in the Raid. Corrosion also gives players water breathing and night vision.

- Swamp: This room follows the swamp genre, with a shallow water layer and slime block. The enemies here are poison-related mobs and Slimes. 

- Frost: The room is covered in a powdered snow and ice layer, with the majority of enemies being frost-related mobs, like Strays and Snow Golems. (P/s: Can we have Iceologer?) 

- Volcano: The room has lava, with fire-resistant enemies. Other mobs can be spawned on the Raid, and gain Fire Resistance from the Corrosion effect.

- Treasure: This room follows the Illager theme.

- Peaceful: Mobs spawning here are passive, such as cow, pig, chicken, ..., or even rare like brown Mooshroom. However, the enemy waves during the Raid are (buffed) Snow Golems, (aggressive) Iron Golems and Wolves.
