Off-hand items can add up to +12 energy inherently. However, there is also a mod which gives the user -1 energy regeneration, or -1 pip, but also adds extra energy.
So far the highest I've seen is +22 Energy, with the inherent +12 from the focus and an extra +10 energy, -1 energy regeneration.
What is the highest amount of +energy that a focus can have? Thanks in advance if anyone knows.

ive got a frost artifact that has +11 with a +13 mod on it, of course it has the -1 regen thing, but anyways +24 is highest i have heard in trades.
