How to use this

Pick up to three monthly missions and this section will tell you which stages can give you the mission reward. The stages are sorted by energy cost; stages at the top of the list will cost less energy than the ones below.

Sometimes the most energy-efficient stages aren't time efficient because enemies there take a long time to spawn (this is especially prevalent in some EoC stages). You can avoid these stages by seeing if the First Spawn condition lists a long period of time. Keep an eye out for stages highlighted in red: this means the enemy spawns on base hit, so you can trigger its spawn without needing to wait for a timer. I would recommend using a soft hitter like Manic Lion (as opposed to something like Maglev) to trigger the base, since minimum respawn mechanics may prevent the target enemy from spawning immediately on base hit.

The Stages in Common section lets you find stages that can clear multiple missions at once. You can mouse any found stages in this section to highlight where they appear on each of the individual lists, and you can click to make the highlight persist. Note that one stage isn't always better than two stages. For example, J K Bun Bun and THE SLOTH both appear in Valley of the End (160 energy), but it's more efficient to do Oil Platform and Enticing Tunnels/Kugel Schreiber (155 energy total). You might also choose to do two stages that are easier to clear intstead of one harder/slower one.

If you enter the number of missions you've done so far (which is listed in the "Clear all Monthly Missions!" mission) then the Optimal Mission Calculator will determine which stage will save you the most energy on average. Like the Stages in Common section, you can hover or click on the optimal stage found to highlight the stages on the individual lists.

If you haven't seen an enemy yet, it will show up as [Unidentified] in the mission text. You can use the Identifying [Unidentified] enemies section to determine what the enemy could be, based on the area and the reward. The Mission Group column can also help to narrow down your choices. The first three missions you get are in Group 1, then the next three are in Group 2, etc. You can also use this section to help you identify enemies in BCJP.
