Did you invest enough into the rune boss appearance rate increase buildings? Cause even if I've maxed out both buildings I sometimes still don't see RB after 6~7 rounds, with that said most of the time I do recognise the improved appearance rates.

Following that statement, I've already amalgamated my LR calamity (around t200 free player RN), and still have 1k in excess of Xmas boxes (I also did all daily before I got a complete 3200 for amalgamation), can't say its impossible, but you need to plan wisely how you consume the free stamina during rune time or save it up until 2x floor event days.
