Talk:"Ayakashi Anniversary Tower"/@comment-108.175.228.98-20140607195018/@comment-24545818-20140608040418

Use the speadsheet to find how much Hp is used to complete the tower from where you currently are.

Then figure out how many minutes are left in the event to find how much of that Hp demand can be met.

The difference in those numbers will need to be made up with your items/level ups. This should answer the "is it possible" question.

Whether it can actually be done by you will take into account your Hp spillover. You will be the best judge of that (your sleeping and other personal circumstances). Any spillover will have to be overcome with your items. Good luck!
