Well you can, but there are other expert packs on the market, such as PO2 which has kappa mode, and Divine journey which is harder than kappa mode. I personally recommend the latter because A. It has a linear progression system with over 800 quests B. Almost all of those quest rewards are either relevant (IE über signaled crossbow) or funny (IE glue balls for making cracked tunic plates. C. Because AE2, and therefore autocrafting, are available meaty at tier 2 two blood magic as opposed absurd amounts of iridium or gems from Neptune, D. It doesn't use power or time as a limiting factor (heck, BR is on the first quest page) and D. It's actually stable, compared to PO2 atleast
