I have a suggestion to give a treasure chest as a reward to the player before they enter into Monolith , these chests will allow you to choose any 3 unique items as a guaranteed reward for you before entering Monolith. Players can use this to drop any build enabling/BiS uniques for their build such as Twisted Heart of Uhkeiros, Ravenous Void, Eye of Reen, Talons of Valor, Omnis, etc.
This change would be done to remove the burden of optimal on CoF players feeling like they needed to level up MG and buy their required unique items in order to play their build effectively.
