Frenzy stored with pockets costs us a total of 30 Orthstirr Pool, which is to say a total of 60 Orthstirr in practice. In exchange, if it's one Frenzy per three pockets, we get 2 Capacity we don't need (from the Infused Hugareida), +1 Endurance (kinda), and a +1 to combat actions. I'd rather have 60 dice than +1 to combat actions by, well frankly by a lot.
If we can store more Frenzy in the same space it's worth it (and we should take Hugr Infusion 2 to test that, among other things), but it's just super not worth it in the long run if it's 60 Orthstirr per Frenzy. I think we still need Fasts and soon in that case. My current plan for next turn is to split the 20d6 I had for Hamr into 15d6 for unraveling pockets (with a note to keep, like, at least 10), and 5d6 for Hamr and continue the quest to raise Hamr and see if the option there is better. Plus getting Infused Hugr 2, of course.
If it turns our 2 Frenzy still fits in only 3 Pockets (and they aren't even full), then it's probably worth it and we can switch to Hugr (plus another turn or two of unraveling pockets).
