While the recently released Radiant Mode was a welcome addition to Darkest Dungeon by cutting down the dozens of hours of grind after you inevitably (and repeatedly) lose a high level group to a total party wipe, it didn't really offer an "easy" mode.
The whole point of this game is the difficulty and setbacks, of that there's no doubt, but there does reach a point somewhere around 30-40 hours in where you've had enough of relentless failure and just want to see the next boss or finally storm that final dungeon.
That's where the Super Heroes mod comes in. See those killer pixelated shade they're wearing? That's because the future is so incredibly bright after modding your heroes to be relentless powerhouses who deal obscene damage. Health loss will no longer be a concern here (although sanity can still cause you to lose all four super powered versions of your heroes, so stay vigilant).
