It actually can and it is wise not to waste crystals when RB appearance rate is low. I am getting used to no RBs for a day or two and then RBs appear quite frequently the very next day or the day after, or vice versa. No crystals would be used while waiting.

I also got pushed out of T300 after doubt pts day this time but managed to come back to T200, with 4 ancient crystals remaining. I am expecting to donate 2 extra normal crystals for this event to stay in rank.

In last tower event, RB refused to appear on the final day and I missed T300. T300 would be nice but T500 is fine. xD

Good luck to OP and wish RBs return soon.
