Energy Fields, also known as E.Fs are auras positioned underneath BOTS to boost their stats. Throughout the early and midgame, E.Fs can offer minor amounts of SpecialTrans, Critical Chance, Evasion & HP. Some Energy Fields are also the primary source of increasing your Luck. The endgame Energy Fields are the primary way to specialize your BOT into a certain stat, with many options being available ranging from E.Fs that boost one stat or others that boost three at smaller increases. Endgame E.Fs become very powerful as they’re upgraded, which is done by collecting fragments from endgame maps and crafting them together.
The permanent & lesser version of the coin-costing Lucky Aura, the Ohka Charm has a low chance to drop from any map in +1, +2 and +3 versions and increases Luck by 20, 30 and 40 respectively.
