Okay, so everyone (pretty much) likes the idea of playing monsters as characters now and then. Including me. But figuring out their equivalent level is tough. Here are a few tips:

1. Ignore CR. The factors that go into making a good challenge and a good PC are so different that, really, CR is no help. Why is that? Good designers know that a monster is only "on the scene" for a very short while -- usually just a few rounds.

So, for example, it shouldn't make much difference to a monster's CR if it has a spell-like ability usable at will or usable once per day. And there's virtually no difference between a monster being able to use it at will and being able to use it three times per day. However, the distinction makes a huge difference when you are a PC, someone who's "on the scene" in every encounter. Further, if a powerful creature has access to a plethora of spell-like abilities (like a balor), that really doesn't affect its CR too heavily, because it will only use three or four of them in a given encounter. But that kind of flexibility matters a lot to a PC. These are just a couple of examples.

2. Read everything the DMG has to say on the subject of balancing races. Then read everything it has to say about balancing classes and levels. The reason for this latter advice is that you need to look at monsters as classes. If I'm playing an ogre, it's sort of like I've multiclassed out of ogre and into whatever class I've taken.

3. Look at a monster's ability score modifiers, Hit Dice, natural armor, damage, and special abilities. Pay very close attention to the following things:

  • Huge Strength (or any high stat, but Strength can unbalance a character the quickest)
  • Spell resistance
  • Damage reduction
  • Invisibility
  • Etherealness
  • Poison
  • Wings

Any of the above factors can throw a game way out of balance very quickly.

The following abilities are more manageable (but still really good to have), because they are less generally applicable or are more in line with abilities that regular characters can get:

  • Elemental resistance
  • Amphibious/water breathing
  • Scent
  • Improved grab
  • Darkvision
  • Skill bonuses (and other things that normal races give a PC)

4. Now, consider the monster's abilities and compare them to the abilities of various classes. Every 2 points of Strength, for example, is almost like a +1 base attack bonus (plus, remember high HD creatures already have a base attack bonus). Spell resistance is a spell that normal PCs don't get until they are 9th level.

Don't be too worried about abilities that work once per day. Having one is a lot like being able to cast that spell (so that's pretty easy to balance). Use the minimum caster level for the ability as a starting point for determining a level equivalency for a monster with magical powers.

Be very worried about spell like abilities usable at will. That's way better than even a high-level sorcerer can do. If I can effectively cast blindness at will, like a nymph (in an area, no less), that's WAY better than being able to cast the spell. The only reason that a nymph might be allowable as a PC at all is because she has to turn off that ability most of the time to avoid hurting her party. The nymph's blindness ability is more like a 6th-level spell, really. And her death-dealing ability is like an 8th-level spell (sort of like destruction, but again, it's in an area). And she can do it all the time. So 15th level is our starting place for a nymph.

On the other hand, she has very few hit points, and no special Armor Class. So 15th level is a little unfair, perhaps.
On still the other hand (we're dealing with monsters, so we can have three hands, right?), she casts spells like a 7th-level druid. So the nymph is like a 7th-level druid with a glass jaw and a couple of really overpowered magic items. Probably something like a 10th-level character equivalent. Even then, I'm not sure I'd allow a nymph PC in my campaign. She'll be killing things left and right, and the rest of the party will have to take steps continually to make sure she's not taken out by even the wimpiest fireball. (The moral: Not all monsters make good PCs, even if you come up with an appropriate level equivalent.)

Let's take another example. Something hard. Something weird. How about a vrock? Okay, he's got 8 HD, so that's a base attack bonus of +8. He's got a +8 Strength modifier, so that's like another +4. Already, he's in the 10th-level range. (Sure, a 6th-level fighter has a +12 attack bonus too, but that's because he's got Strength-enhancing magic, good feats, and a good magic weapon -- the vrock can get all those too.) He doesn't have the feats of a fighter, though, but he does have lots of natural attacks that do decent damage. That's almost a wash. So he's sort of like a 10th-level fighter, let's say.

But he's got SR at 22. A 11th-level cleric casting spell resistance gets SR 22, and that's got a shorter duration. He's got damage reduction 20/+2, so that means that he can ignore the attacks of your average low-level fighter or dire animal. Just ignore them completely -- like they weren't even there. And, holy cats! He can cast mass charm at will. He can cast mirror image and teleport without error -- at friggin' will. That's all beyond a 12th-level fighter. Couple that with tanar'ri resistances and immunities, and the vrock's more like a multiclass fighter/sorcerer 10/7. At least. So I'd say 17th level.

So would a vrock make a good 17th level character? I'd say probably. He won't be nearly as good a fighter as the fighter, and he won't be nearly as good a sorcerer as the sorcerer, but he's got a lot of flexibility (and a smart player will have a field day with teleport without error and mirror image at will). So, I'll stand behind that 17th-level figure and would happily play a vrock in a 17th-level party.

So there you have it. Some things to think about as you get started. Is it easy? In a word, no. It's very hard. Look at every factor of the monster, and make lots of comparisons to things already in the system. Good luck.
