Wipe Block
The main job of the wipe block is to even out the start and make the beginning of the wipe staged. Players are placed into equal development conditions and get a chance to fortify themselves better before the future raids.
After a wipe, weapons, armor and raid options aren't immediately available — they unlock in waves. You can craft or pick up an item at any time, but you can only actually use it after it's unlocked. Locked items are marked in the inventory, and the current status can be viewed via the /menu command, in the Wipe Block section.
