Well, we've heard a number of calls from DMs for a preview of the guidelines for designing and balancing encounters, so let's take a look at those rules this week. You can use these guidelines with the monsters in appendix B of Lost Mine of Phandelver to continue your campaign or create new adventures.
As a general rule, monsters with a CR higher than a party's level pose a significant threat.
multiply the XP value of an encounter by 1.5 if the monsters outnumber the adventurers by two-to-one. If the monsters outnumber the characters by three-to-one, multiply the XP total by 2. For a four-to-one advantage, multiply the XP total by 2.5, and so on.
What should we expect from a 'challenging' encounter (assuming no CR is greater than party level and PC are not outnumbered)? Is it likely that one or more PCs will die in this encounter? In order words, what type of encounter should be the most commonly used? Thanks.
They don't say, but they do note that PCs can likely only survive 2 hard encounters worth of XP per day before being entirely out-of-resources (i.e. "needing" to take a long rest). So it would presumably depend on how many encounters/day you expected the PCs to hit. Approximate figures - 2 hard = 3 challenging = 6 moderate = 9+ easy (varies a lot by level). Thus I think it's safe to say moderate is the expected default.
