Potion Berwing Upgrade and cobblestone (obsidian) generator Upgrade

[penutbutterjelly]

Got to love the mod i just can't leave with out it, I put it on almost all the mod pack that i can put in and great job on making it.
so here a idea Potions Brewing Upgrade (this one first) and one more a cobblestone generator Upgrade in the backpack with a option to make both cobblestone (infinite) and obsidian (consume both water and lava) hope this help with some ideas for future making for the SophisticatedBackpacks
