How to increase the Inventory Box size?

[Cepat]

I'm trying to add Din's Fire to my quest but somehow the current Inventory Box is not large enough to accept that item. So my question is how do I increase the Inventory Box? Thanks :)

If you're using the latest beta, in quest rules select the new new inventory, and that should do it.

I just found out in Init Data, go to last page & select Revision 2.
Thanks anyway.
