I am trying to pit a party against a powerful, epic-leveled Goliath Barbarian, using the abilities he would have as a player character. I do not want to make him too powerful, but I still want him to reflect the epic status he is supposed to hold.
Are there guidelines for how to calculate this challenge rating?
Notes:
- I'm not horribly interested in frame challenges here, unless there's a really good reason for it. This is a casual one-shot for my family, not an AL public game.
- The party will be from 4-7 people, all at level 3. One of them (my dad) played in college, so several editions ago, and other than that, there's very little experience with the game. I don't know how useful this is to answerers, but my goal is definitely to err on the side of easier, rather than harder, because of their lack of experience.
- For those familiar with it, I'm going to be using the Tal'dorei setting (specifically Whitestone during Winter's Crest) and pitting the party in a recreational fight against Grog.
- Despite all of the specifics, I would love to get my hands on a formula that I can use in the future.
