Encounter Management (5e)
This is a fillable encounter management that has auto-calculating stats. It lets you design/populate encounters for monsters of up to three distinct types and up to seven of each type (allowing for up to 21 monsters per page). It includes an Initiative tracker and a small notes section for loot¸ NPC motives¸ or whatever else strikes your fancy. This is a modified version of the work started by Neskatomon and Master Herald in this reddit thread.
