regarding the collection of skeletons in "Mr. Skelet Revenge".

2) Of course, visiting the hideouts of demons, abandoned mines, and griffin conservatories. If anyone hasn't noticed, at the end of the path, there are 3333 archmages. That's quite a few skeletons too.

It turns out I messed up not only with the boots :) I didn't reach the very last castle and didn't see these archmages.
PS. Thank you for the advice. I think it will be interesting for more than just me to know this.
