Gauging an encounter’s strength in 5e can be a lot trickier than it seems at first glance. The provided encounter builder in the DMG, as well as the Unearthed Arcana encounter builder, can provide a baseline for how strong monsters should be to challenge the party. Unfortunately, the provided tools don’t scale well as the party levels up or adds new members - especially not post introduction of magic items. For that reason, I’ve built an enemy calculator that can be used to more accurately balance encounters. I plan on adding more features and slowly refine the tool over time.

Enjoy!
