You are trolling if you are not using essences and actions in Delubrum

Now I would never expect this in a random DF group. This party was advertised in PF specifically to trash bosses. With that said though, I do think Essences should have been made mandatory for queuing simply because the bosses are scaled with the belief you'll have them. Part of the fault, however, lies on the devs for not better incentivizing them. Far too few fragments drop from DR itself. They also missed a perfect opportunity to stuff low grade Essences in lockboxes instead of yet more useless prisms

See there lies the problem the Devs. Sounded good on paper but put into practice not very good.
