I've been growing a bright node using the 7x7x7 box method with the bright node in the exact center over the past 4 days (on a server), and the node is now a bit over 100 vis for most of the aspects. I should get an 11 or so energized node out of this when it finally consumes all the feeding nodes. While I've been waiting for this to grow, I found and jarred a lucrum node, which breaks down to all the primals. I ended up with a 3 energized node from this. With it, I've set up the wand recharger, an advanced alchemical furnace, an infernal furnace, and even feeding my arcane bore (mushroom farm). My question is, why do I need a 10+ energized node? Everything appears to be running just fine off of the 3 energized node. I know my wands and amulets will charge faster from it, but besides that, what benefit can I see? And related to this, is what is actually needed to run each machine?
