good to have in estimating LM, Mission and NPC drop rates and energy used during a mission

-1 for uselessness.

completely unnecessary to calculate drop rates. look at your NPC stat before you start your NPC run. look at it after you have completed LM or mission. drop rate calculated. done.

as for energy used during a mission ? it states the energy requirements for each round on the mission itself. and if you don't have enough energy to complete a legion mission task .. you need to add more engineers. grill a few tacos next time.
