Another flower, a spark augment, something added onto the corporea system, a new mode for the Wand of the Forest... I honestly don't know... Maybe a Dreamwood wand of the forest allowing the flowers themselves to output a relative strength redstone signal with a special mode? 0 mana = 0 redstone. 1 mana to 6.66% full = 1 redstone, etc up to 100% (only) being 15. I've never liked the fudge factor in a couple of comparator outputs where 0 is output at a range, and 15 at a range. 0 should only ever be 100% empty and 15 should only ever be 100% full. If you want to get "mostly empty" that's what 1 is for, and "not quite full but really close" is 14. (I'm looking at you Thermal Expansion Energy Cells... *grumble*
Oh speaking of sparks, is the dispersive spark augment faster than a mana pool at charging items, and do multiple dispersive augments stack for charging rate? I'm asking mostly because of the terra shatterer. I could easily make a rig to just keep it atop a mana pool fed by sparks and such in a chunkloaded area, refreshing it every 4 minutes... but that strikes me as rather cheaty if I can just use spark augments to do it "legit".
