Energy Gear is a unlike your regular everyday fighting gear and is often not very effective in battle. It instead, caters more to you whilst you're asleep or away from the Spiral for a while... Energy Gear is gear that adds to your max energy which lets you build up more energy during downtimes. If you can get the right gear, you can increase your max energy by huge amounts, up to even 234 at the very, very highest (includes sockets).
There are all sorts of energy gear and you can get the energy bonuses on all gear excluding decks, wands and mounts. You can even receive energy from pets such as the Dapper Corgi! Energy gear is any gear that gives you increased max energy, meaning you can build up more energy whilst equipping this gear. An example of when this is effective is whilst you are offline, you can build up energy for gardening, fishing and pet training.
There is one final piece of advice that I have for anyone buying energy elixirs. If you are going to buy an energy elixir, make sure you get your energy down low first than make sure you've got your energy gear equipped. This will again, give you more energy.
Well, thanks for reading and I hope you enjoyed!
Until next time!
