The Psychon is a new class for D&D 5e and Pathfinder that combines the sturdiness and damage dealing potential of a Fighter or Barbarian with the flexibility and support potential of a summoner. The pdf contains both D&D and Pathfinder versions.
Some time ago — jeez, years ago, really — one of my D&D playmates, J, was frustrated with his character build. He often has this problem. The classes in D&D just don’t always fit his concept of what he should be able to do. Really, J would benefit from playing a different game rather than trying to shoehorn his concepts into D&D, but that’s neither here nor there. Our group plays D&D/Pathfinder, and it’s pretty rigid on that choice. So what was an amateur game-designing GM to do? Design a new class, of course!
Now, J likes to be a front-line fighter, doing massive DPS. But he also likes to use summoning spells to bring helpers on the field to annoy the enemy. He was trying to play a Fighter/Cleric multiclass but grew frustrated with only having access to level x Fighter or Cleric abilities at level 2x. He also had little patience for casting spells beyond summoning and hated having to bother healing people. It was a bit frustrating for the whole table.
So, I set myself the task of designing a class that could hold its own as a Fighter-style front-liner while still having the ability to summon helpful creatures, but without simply mashing together some sort of gestalt Fighter/Cleric. This was likely going to be used for a D&D 5e campaign, and that would be way too OP. But, there was also a chance it might be used in a Pathfinder campaign. Our group rotates through three GMs periodically, so GMs can have a break, and at the time, two of us were running Pathfinder, while I was dragging the group into 5e. So, I started with a Pathfinder design, then pared it down for 5e. I think the 5e version might be better balanced than the Pathfinder version because of that. It’s been quite a while since I started the design, and I’ve dusted it off recently to present it fresh to my tablemate. He’s about to run a 5e Psychon character now, so there will be some actual playtesting. Other than that, balancing and playtesting have been theoretical, so only use this class at a table that isn’t too worried about balance, or at least has a spirit of design that will allow for tweaking as you go.
