[MIRROR] Blade creation ritual returns lost blades (#2482)

* Blade creation ritual returns lost blades (#82592)

## About The Pull Request

Blade ritual now break first created blade if limit and create new one.
If someone was on a tile with a blade, their hand would be cut off

## Why It's Good For The Game

If heretic loses his blades, then due to the limit on creating new
blades, he will not be able to make new blades for himself. Now, you can
return your blades.

🆑
balance: Heretic now can return his stolen blades by using blade
creation ritual again.
