This is something I can focus on now that Morostide is over (and I have plenty of hours to dedicate to this). I'm going to get with Cranberry and Purge and discuss a few suggestions here. :)
That's actually something and I have been discussing; having the potions and pylonics have a chance of going out via battle quests as bonus items. I just have to investigate a bit more how the quests are set up and how easily I can add those in as additional prizes rather than adding it to the current pool. :)
