NPC Importance

( ⇪ House Rules )

To distinguish how capable a creature is, certain adjustments are made to their normal stats and abilities. There are major NPCs/enemies, Average NPCs/enemies, and minion NPCs/enemies. Minions are a carry-over from D&D 4th edition and can be used in large quantities to fill out the remainder of an expected challenge. At all levels, four minions combined should roughly have a CR equivalent to a single average version of that creature “per PC”.

Minion NPCs

Minion creatures and NPCs…

  • have an initiative of 1+mod (is not rolled, is after all PCs/allies on that number)
  • have half as many Hit Dice (round up to the nearest HD step), for effects that care about hit dice
  • have full hit points, but their hit points drop to zero very easily (see below)
  • have no action points.
  • have a tiny number of save points (see below for how many)
  • might at-best have a few NPC class levels, but usually have no class levels at all
  • drop hit points to zero instantly if
    • it takes any damage from getting hit by an attack, but never takes damage from missed attacks
    • it takes any damage as the result of a failed saving throw, but if they save for half damage they instead take no damage
    • it takes damage from another effect (such as caltrops or magic missile) which equals or exceeds their hit point maximum, otherwise they take no damage.

Minions always deal average (mid-point of the die curve) damage rounded-down, and can’t score critical hits.
Xd4+Y = 2.5X (rounded-down) + Y
Xd6+Y = 3.5X (rounded-down) + Y
Xd8+Y = 4.5X (rounded-down) + Y
Xd10+Y = 5.5X (rounded-down) + Y
Xd12+Y = 6.5X (rounded-down) + Y
Xd20+Y = 10.5X (rounded-down) + Y

PCs cannot acquire or control minion versions of a creature (they’re either too fragile to submit, or too weak to be convinced), as minions are strictly something only the GM should control.

GM’s Note: Minions tactically will frequently take the aid another action (rolling against AC 10) to benefit an ally’s attack score or AC, but they have to be within melee range of an opponent who is within melee range of their ally. They will also take the aid another action on an ally in order to draw the opponent’s attention, or use intimidate to demoralize an opponent if they can’t get to within melee range. Minions will typically prioritize aiding their commander (a non-minion) in this way instead of another minion.

To determine how much minions cost your budget:

  1. Get the CR of the listed version of that creature and find out how many of that would fill out your budget, as a starting point for judging difficulty. For example, if you have an enemy which is listed as CR 1/2, four of that listed creature would be enough to fill out an average challenge for an ECL 1 party, and six of them would be enough for a major challenge (although if you were to actually do that each creature’s CR would change, see below).
  2. Determine the CR of a set of 4 minions of that creature, and figure out whether you just want to fill out the budget with average and minion versions of that creature. For example, for an listed enemy with CR 1/2, that’s the same as saying four minion versions of that creature is CR 1/2.
  3. As per the Monster Challenge Ratings section of the Bell Curve Rolls variant, when encountering four or more of the same creature, reduce each creature’s CR by 1 step. Usually you’ll do this to minions, not average creatures.
  4. With that possibly-reduced CR for having at least 4 of them, fill out your budget.
For Example: Let’s say we want to create a major challenge for an ECL 1 party, consisting of a CR 2 evil cleric and a bunch of minions, and some of those minions are the cleric’s commanded undead. The budget is 900 XP.
The CR 2 cleric uses up 600 XP of that, so the remaining budget is 300 XP.

An evil cleric can command any number of undead whose total Hit Dice do not exceed his level. Minions count as only 1/2 their Hit Dice for the purpose of effects which care about that. A skeleton has 1 HD. That means the cleric could command four skeletons, for a combined CR as minions of 1/3, reduced to 1/4 because there’s 4 of them, so it’s 75 XP. We have 225 XP left.

We can make the other minions cultists who have the stats of human warriors, each with a listed CR of 1/2. Four minion human warriors is the CR-equivalent of one listed human warrior (150 XP), and since there’s 4 of them you drop the CR of the set by by one step (100 XP for four) and CR per minion to 25 XP. Nine minion cultists would total 225 XP.

So one evil cleric, four skeletons, and nine cultists. That sounds like a pretty major encounter for a level 1 party to me. However, realize that Area-of-Effect effects (like a burning hands spell or gun) can wipe out swaths of minions all at once. The Reflex score of the skeletons is 12 and for the cultists it’s even less. A typical level 1 character can afford a CL1 burning hands gun, which gets a +1 to the effectiveness roll. That means they have a 50% chance of rolling high enough to kill any one of the minions in the AOE, although you’d still get to roll the Reflex Check for each minion.

Average NPCs

Average NPCs and creatures that are more important than minions but aren’t really important have stats just like the original creature. Their initiative is 11+mod (is not rolled, is after all PCs/allies on that number). They are forbidden from having gestalt levels or optimized builds, might at-best have non-NPC class levels, and use the average array of ability scores (10s and 11s, not counting ability score increases from existing Hit Dice and racial bonuses).

They may optionally have the nonelite array and a single action point if they need to last a while.
The nonelite array is: 13, 12, 11, 10, 9, 8. The nonelite array does not necessarily make a monster better than normal, but it does customize the monster as an individual with strengths and weaknesses compared to a typical member of its race. Be sure to account for ability score increases they’ve already taken from having existing Hit Dice when applying the nonelite array.

Giving an NPC even a single action point may result in situations which look like you just fudged the Target Numbers the players are rolling against. For example, if they hit the NPC on a 15 but then didn’t hit on a 16, they’re going to be suspicious. Regardless of whether you actually fudged the numbers, or whether all you did was have the NPC use a Total Defense Action , action points represent the heroic side of an NPC (or at least, what they perceive as heroism). It’s thematically equivalent to how PCs can spend awesome-marks on each other to give a temporary bonus: the NPC has allies rooting for them too.

Major NPCs

Major NPCs have all the same stats as the original creature (including initiative being 11+mod, is after all PCs/allies on that number), plus the elite array and 2+(0.5xECL) action points. They frequently have gestalt levels and/or an optimized build.
The elite array is: 15, 14, 13, 12, 10, 8. While the monster has one weakness compared to a typical member of its race, it is significantly better overall. Be sure to account for ability score increases they’ve already taken from having existing Hit Dice when applying the elite array.

Default NPC Save Points

Adjust the save points of NPCs and monsters to meet the needs of your desired difficulty, but the importance of the enemy should affect the amount of save points you use “by-default”.

19 or more 50 + 5×[Base Save Bonus] 50 + 5×[Base Save Bonus] 50 + 5×[Base Save Bonus]
GM’s Note: The math for this is
  1. Determine their Base Save Bonus for each save (subtract Ability Modifiers).
  2. Determine their maximum save points for each save (50 + 5×[Base Save Bonus]).
  3. Estimate their default save points for each save, as given in the table below:
    • For minion-like NPCs/enemies, use 15+(CR×CR/10).
    • For NPCs/enemies of average importance, use 15+(CR×CR/5).
    • For major NPCs/enemies (like bosses), use 15+(CR×CR/4).
    • Finally, for all NPCs/enemies, add an extra 5×[Base Save Bonus].
(The calculated value should not exceed the maximum value.)
