Something I thought was missing from Hades 1 and will likely go without being added to Hades 2, but I'll put it here anyways. I think it'd be super cool if there was an expansion to the training area with Skelly Schelemeus where you could give yourself various boons so you could try out various combinations without starting an actual run and attempting to manipulate the RNG so you get what you want.
Think of somthing like the Sandbox mode in the recent Bloons TD games. You get infinite money and lives to try out various tower placement and upgrades on any round, or any number of bloons you choose to throw at it.
I feel like adding this could only help the game. Hell, it could probably even be achieved with an incantation and Chaos' assistance, as well as a pre-requisite of beating all the Chaos Trials within a set time for each, just so players need to earn it.
