So how should I build my encounters under these rules? Well, the format should allow you to build a traditional one single, tough and strategic encounter (4th edition style) - but also a number of encounters or “waves” as pemerton refer to them (more 5th editon style). I will still call them encounters, because I like to see encounter powers’ effect end at the end of them, rather than lasting through three “waves” within one encounter.
SINGLE Encounter
The single encounter is exatly that - one tough encounter the party faces before getting a chance to take a one hour Short Rest.
Level: Based on my calculations, it looks like the preferred challenge should be a monster of the player’s level + 1.
Length: The battle will last for 3 rounds at first level, 4 rounds at 5th and then 5-6 rounds at level 15-25 (see below).
HP: It is going to be a though fight with roughly 8% of the HP remaining after the battle (excluding any healing done during the battle).
Powers: Rougly one daily will be used and all encounter powers, and the players will have to use one At-Will power before finally finishing the battle and defeating the foe.
DOUBLE Encounter
If we instead look at running two encounters before the short rest and having them equally though we have to find a weaker opponent in each encounter.
Level: Based on my calculations, it looks like the preferred challenge should be a monster of the player’s level -2. (Alternatively running a 5 player encounter against 3 monsters of equal level to the PCs.)
Length: The battle is now shorter. It will last for 2 rounds at first level, and 4 rounds at 5th, 15th and 25th level (see below).
HP: It is going to be a simple fight with roughly 58% of the HP remaining after the battle (excluding any healing done during the battle).
Powers: Here we start to see the impact of the limited encounter resources. As these are simple fights, the party will most likely not use a daily. The graph below assumes the use of dailies as well as encounter powers, but as the total number of rounds is actually 2+2=4 at first level, and 4+4 = 8 rounds at the other levels, the encounter powers will not last. Most likely only 2 encounter powers will be used at higher level, and the rest will be At-Will powers. Conclusion is that we will have to recalculate the graph below to better reflect the encounter power used in the two battles.
