Energy Factor (EX)
The energy factor is a derived trait representing your energy potential.
Most sophonts start the game with EX = 2.
Maximum Energy Points (ep,max)
Your EX affects your maximum energy points (ep,max), which are found by:
note
ep = EX • (1 + M(Energy))
That is, add 1 to your Energy modifier, and multiply the result by your EX.
Energy Point Recovery (ep/r)
Your EX also affects the rate at which your energy points recover after a rest (ep/r), which is found by:
note
ep/r = EX + M(Energy)
That is, add your Energy modifier to your EX.
