It's 13d 9h. Yeah. The tower has been like that for awhile now, sadly, requiring more HP than the natural HP regen the whole event duration can offer.

At least from the previous tower event, you will gain a total of 10,940 EXP from floor 1 to 200. I'm not sure of the EXP requirement for Lv66, but I guess you can try estimating it once you level up to 67.
