I have designed an App, RPG Online Tools, for RPG fans that does the calculations of damage per round for Attacks or Spell attacks, so you can min-max to your heart’s content. Included are rules for different gaming systems including D&D 5e, Pathfinder 1e and Pathfinder 2e.
Also included is a random Plot generator, for when you want a quick plot hook for a min-encounter, or as inspiration for a full “home-brew” campaign.
Finally, there is a random Encounter Generator for Pathfinder 2e rules, complete with area descriptions, creatures, traps and treasures.
Hope it helps!
