Crystal Fortress

Crystal Fortress is a large structure in very early War Mode (just after Wall of Steel). A rift will appear in a random location in the world (it CANNOT be in a depth below 0, or inside blocks) which will teleport you to the fortress. The fortress has 4 challenges. If you get through all four challenges unscathed (meaning no deaths), you get 9 Platinum Coins and a Legendary Star Wrath. Otherwise, you will get a regular Star Wrath and 1 platinum coin. You don't have to do anything to enter the challenge, just be prepared enough (especially for Challenge 4, Floor Mayhem)

It has a crystalline theme. Using pearlstone blocks and Hallow crystals, their only difference is the fact they cannot be broken.

Challenge 1 (Challenge of the Meowmere)
The Meowmere must be used to defeat 5 waves of 100 enemies with 600 HP each and 100 attack damage + defense. No mounts can be used. The player will automatically be healed 200 HP inbetween waves and a wait time of 30 seconds.

Challenge 2 (Challenge of the Armorless)
A gold broadsword combined with no armor must be used to complete enemies of 3 waves of 7, each with 30 HP, dealing 40 damage and 0 defense.

Challenge 3 (Challenge of the Jumpless)
The player gets their weapons and armor back, but has greaves that do the same defense as a Breastplate but extremely limit the jump to a useless amount of only 0.01 blocks. They are a green version of silver greaves. Players have to face jumping enemies that have 500 HP, deal 300 damage and have 5 defense.

Challenge 4 (Challenge of Floor Mayhem)
The player's items are taken and stored into a chest. Then, the player will be downed to a total of only 1 HP and placed onto a gold brick platform. Then, unattackable passive enemies with 1 HP will be placed on gold brick platforms.

It plays out like Lab Experiment in which random things occur to the platforms or players, such as expanding, bridging, merging, rotating, and vanishing. However, the platforms cannot have direct negative effects to the player's luck, such as shrinking. Like Lab Experiment, however, there is lava but unlike Lab Experiment the lava does not rise. And, obviously, it is two dimensional unlike Lab Experiment.

It is very hard to pass the challenge because of the fact that something unpleasant may happen to your platform first. Being the final challenge, it is very hard to pass.

Once the challenge is complete, the player will have their items back from the chest.
