This is a variant rule that is mostly to help dungeon/game masters coordinate about how many encounters on average there should be per day.
The barbarian's Rage class feature has a set of uses/day that doesn't work like most systems of number/time interval. While the barbarian of a higher level can rage, say, 3 times per day, he can only rage once per encounter as per RAW. I found that very interesting, and came up with two questions:
1.) Would it be okay for there to be too many encounters for a barbarian to be able to rage in per day? A barbarian that can't rage or is being "strategic" with rage uses is just stupid- if you're a barbarian, you probably don't want to be that strategic in anything.
2.) What if there were fewer encounters per day than there were uses of rage? Would the barbarian then feel let down upon gaining a level when all he got was another use of rage that he doesn't need?
So then I came up with a theory in which you should try to shoot for X number of encounters per day, where X is the number of rages a barbarian whose barbarian level equals the party level. With this in mind, it becomes more feasible for DMs to figure out how much is too much or not much for the party to handle (whether they use that knowledge to not overburden the party or to tire them out on purpose).
Sidenote: Extra Rage feats
The Extra Rage feats from PHB II and Eberron Campaign Setting show a big hole in this planning strategy. This gives the DM a few options:
- 1.) Add 2T to the aforementioned X every three levels, since the feat grants two extra uses of Rage per day. T=the number of times a character could possibly have taken the Extra Rage feat.
- 2.) As number 1, but only if a barbarian takes the feat in the first place.
- 3.) Ban the feat from the game.
- 4.) Instead of more encounters, provide options for a barbarian to rage in order to assist in tasks while not in combat, such as an interrogation, or to break down a door. This is my favorite option since my campaigns are rarely combat-only.
So that's basically the gist of the idea. What's your guys's take on this? I'm posting this specifically because I'm not sure if I should go and make decisions based on this or not.
