Quests and puzzles!

This bug is actually used – and it’s not prohibited in online play! ...

In virtually all rulesets, this bug is prohibited. ;)
Among those dinosaurs who still play Heroes of Might and Magic 3:D

And if it’s allowed when solving the puzzle, then the very first thing I wrote will work. Ciela and Ballista + 2 Fairies kill 6 Psychos, and that’s it. And Graig will disappear. Anton didn’t mention this for some reason.
I just have it ingrained in my mind as an online player that you shouldn’t use such a bug. :)
