I can give you a creaturescript that refills good war backpacks for each vocation based on minimum level 70 (else you cant cap it). It includes basic runes like uh, sd, gfb, manas, magic walls. More opinional runes like fire bomb, destroy field, desintegrate. Rings, amulets, items, pots and more. All multiple bps like manas are within each other 19 runes then next bp. You just need to add one storage value when player logs in the first time and one when they die.
Would be possible to use non infinite supplies setting with such backpacks.
