There is exploit:
use containers of creatures (eggs, coffins, etc) with random number of creatures. example: snake eggs (generate random number units). dragon eggs does not approach (generate 1 units).
It will change "random sid" for scroll.

example:
- save game
- use scroll
- creatures not approach
- load game
- use 1 snake egg
- use scroll
- creatures not approach again
- load game
- use 1 snake egg
- use 1 snake egg again
- use scroll
...
etc
