So an issue that basically everybody runs into if they do the minigame is that everything worth getting for a non-iron is based on it's lye cost. Because all the uniques are lye heavy and the only things that are not lye heavy are not worth the lye used to buy them (adept come close at 600gp per lye vs aldarium's 690). So unless people engage in the act of curating what potions they turn in (which is against the design/intent of the minigame from my understanding) or do the minigame before unlocking anti-leach-lotion(ALL) at lvl 78 then they will end up with an excess of mox and aga resin and nothing to actually do with it.
The potion packs seem like the perfect option for cashing out on excess resins. Apart from the prayer regen potions in adept and expert all they give is just standard potions. It would slightly increase the rate of regen potions appearing on the market because it would me that people who are focusing the untradeables/clogs would also be outputting some amount of prayer regens.
From looking at the current costs of the packs in the diverse resin types it seems that for all three types the amount of resin to make them should be somewhere between 600 and 800 if they were only using the resin of their tier.
So apprentice potion packs costing mox, adept using aga and experts of course using the mighty lye. Which probably means experts are not going to be used except by ironmen.
