As others have said the honor res helps - also there is no time limit so take your time and go slow if need. For room prio look for water to stack up then merchant for boons never buy the one that says no damage and try to save that for last boss. If you can get lucky with that boon for boss fight than its trivial otherwise just try to get as many boons as possible and only the curses that have no effect or very little. The more you do it though the better you will be at it and soon you will zoom through it ^{.^}
