Questions and answers about ERM scripts for WoG.

Drkolichi:
appear 3 in the dragon cave.
Artifact:
1. 90% less sum paid when surrendering (this is in the total amount).
2. If in the city, it increases growth by 50%.
3. +1 to battle spirit.

I'll do it, but it won't be possible to place Drkolichi in the dragon crypt.
I can make it so that they are purchased by clicking on some icon.

And a question:
can't it be made so that the catapult attacks creatures?

It's possible, because it exists in WOG (Scripts: Improved Military Machines 1 and 2).

Yes, regarding the arena: I can make it so that the commander fights monsters (their number and level depend on the commander's level).
