Data - Base Order ID? What exactly is this?

* i search the forum but i didn't get to find any info on this. Only manage to found out how it is use to play around with Spell Book.
* sorry i am not sure if this should go here or in the general since it is under object editor.

I notice this in the Spell Book item ability. And i read about how it works if we change the Order ID so that it won't stack as one same spell.

But what exactly is Base Order ID? if i change it to "berserk" will it affect the "berserk" spell?

Example:
If i change spell book base order id to berserk, and i have a berserk spell, will it affect the spell book when i cast berserk or vise versa?

Thanks in advance!

I would assume it would, since the spellbook would get 'berserk' as its order ID.
