Is there any way to finish Hard mode without using the 'keep your rerolls at end of turn'? It seems the price-of-entry, given all the bosses with 'damage cap 3' and 'you only have 2-3 turns to kill 2 bosses, plus most of the other enemies'

Well played - very impressive! Time Vessel is definitely one of the top relics. It would be interesting to hear what other players think - do you think it is mandatory for HM Chaos Realm?

On discord there are people posting scores in the 100,000's :) - but once you get past about 2-4k its easy to go a long distance
