I'm currently working on a modified 5E that uses 1/encounter abilities (and at will abilities). Taking inspiration from 3E ToB, but as well as stances, boosts, counters and maneuvers, spells also fit in this category.
For example spells like mirror image, blur, stoneskin etc become stances, shield becomes a counter etc.
I'm trying to do away with daily resources as much as I can, to do away with the 5mwd.
Exhaustion and Hit Points are my current 2 bugbears. I'm struggling to make them encounter based only but am mulling over a few ideas.
I'll post it here when I'm done.
14 days in quarantine needs to be spent doing something.
What a time to be alive.
