Monsters As Races
While every monster has the statistics that a player would need to play the creature as a character, most monsters are not suitable as PCs. Creatures who have an Intelligence score of 2 or lower, who have no way to communicate, or who are so different from other PCs that they disrupt the campaign should not be used. Some creatures have strange innate abilities or great physical power, and thus are questionable at best as characters (except in high-level campaigns).
Starting Level of a Monster PC
Monsters suitable for play have a level adjustment given in their statistics. Add a monster’s level adjustment to its Humanoids and Class Levels to get the creature’s effective character level, or ECL. Effectively, monsters with a level adjustment become multiclass character when they take class levels. A creature’s “monster class” is always a favored class, and the creature never takes XP penalties for having it.
Humanoids and Class Levels
Creatures with 1 or less HD replace their monster levels with their character levels. The monster loses the attack bonus, saving throw bonuses, skills, and feats granted by its 1 monster HD and gains the attack bonus, save bonuses, skills, feats, and other class abilities of a 1st-level character of the appropriate class.
Characters with more than 1 Hit Die because of their race do not get a feat for their first class level as members of the common races do, and they do not multiply the skill points for their first class level by four. Instead, they have already received a feat for their first Hit Die because of race, and they have already multiplied their racial skill points for their first Hit Die by four.
Level Adjustment and Effective Character Level
To determine the effective character level (ECL) of a monster character, add its level adjustment to its racial Hit Dice and character class levels.
Use ECL instead of character level to determine how many experience points a monster character needs to reach its next level. Also use ECL to determine starting wealth for a monster character.
Monster characters treat skills mentioned in their monster entry as class skills.
If a monster has 1 Hit Die or less, or if it is a template creature, it must start the game with one or more class levels, like a regular character. If a monster has 2 or more Hit Dice, it can start with no class levels (though it can gain them later).
Even if the creature is of a kind that normally advances by Hit Dice rather than class levels a PC can gain class levels rather than Hit Dice.
The creature’s Hit Dice equal the number of class levels it has plus its racial Hit Dice. Additional Hit Dice gained from taking levels in a character class never affect a creature’s size like additional racial Hit Dice do.
Feat Acquisition and Ability Score Increases
A monster’s total Hit Dice, not its ECL, govern its acquisition of feats and ability score increases.
Ability Scores for Monster PCs
While a monsters statistics give the ability scores for a typical creature of a certain kind, any “monster” creature that becomes an adventurer is definitely not typical. Therefore, when creating a PC from a creature, check to see if the creature’s entry has any ability scores of 10 or higher. If so, for each score, subtract 10 (if the score is even) or 11 (if the score is odd) to get the creature’s modifier for that ability based on its race or kind. Generate the character’s ability scores as normal, then add the racial ability modifiers to get their ability scores.
Note: Some monsters have base ability scores other than 10 and 11. If alternate scores were used this will be indicated in the monster entry. Also, some monsters that make good PCs have their racial ability modifiers and other traits already listed in their monster entry.
For ability scores lower than 10, the procedure is different. First, determine the character’s ability scores, and compare that number to the monster’s average ability score, using either the table below that applies to Intelligence or the table that applies to the other five ability scores.
The separate table for Intelligence ensures that no PC ends up with an Intelligence score lower than 3. This is important, because creatures with an Intelligence score lower than 3 are not playable characters. Creatures with any ability score lower than 1 are also not playable.
|Generated Score||Monster Intelligence Score|
|Generated Score||Monster Ability Score (Str, Dex, Con, Wis, Cha)|
Other Statistics for Monsters
Creatures with Hit Dice of 1 or less have normal, class-based Hit Dice and features. They get skills and feats appropriate to a 1st-level character (even if they have a level adjustment).
Those with 2 or more Hit Dice have statistics based on these Hit Dice plus Hit Dice for class levels (if any).
Experience for Monsters
A monster with Hit Dice of 1 or less, no level adjustment, and class levels uses the same tables as standard PC races when determining experience needed.
A monster with Hit Dice of 1 or less, a level adjustment, and class levels adds its class levels, and level adjustment together when determining experience needed (class level + level adjustment).
A monster with more than one Hit Die, a level adjustment, and class levels adds its Hit Dice, class levels, and level adjustment together when determining experience needed (HD + level adjustment + class level).
