The new Crucible mechanic is more about crafting, but how exactly does it work?
How the Crucible Mechanic Works in Path of Exile 3.21
The recently released Crucible league for Path of Exiles 3.21 update features a brand new mechanic that focuses primarily on crafting powerful weapons.
In a way, it gives players a chance to craft powerful mirror-level weapons that can easily surpass any crafted weapon in the game so far.
This is due to the fact that you can add passive skill trees to your chosen weapon via the new mechanic.
