I like this game and the energy system which does make me stop playing to kick back until my reserves come back. But I wonder how long does it take to get from 0 to 100 energy in real time?
When is the soonest I can get back into the game and craft my "insert sword" with the money I got from playing "insert level dungeon" so I can equip it and level it up?
It takes 22 hours to fully regain 100 mist energy.
Personally, I would advise not crafting anything until you're well into T2. Merchants and crafters have been (unintentionally?!) coordinating to cause the price of 0-2* equipment to drop lower than the energy cost required to craft them. You should take advantage of this and save your energy for dungeons instead.
