I#ve got an important question. As a priest or wizard you can research new (and existing) battle spells. As I know, those who have material components, are very expensive. For "bark skinned unit" you must cut a half forrest for example.

Now my question:
Is it possible to write battle spells as scrolls? Normal spells consume material components in their creation, but the above half wood (Might be a little difficult)? Further you need additional priests for help, do you need them, when scribing the scroll?
