MONSTERS AND CLASS LEVELS
The creature's Hit Dice
equal the number of class levels
it has plus its racial Hit Dice
. A creature's "monster
class" is always a favored class
, and the creature never takes XP penalties for having it. Additional Hit Dice
gained from taking levels in a character class never affect a creature's size.
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.
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
. The monster
is considered to have experience points equal to the minimum needed to be a character of its ECL.
If you choose to equip a monster with gear, use its ECL as its character level for purposes of determining how much equipment it can purchase. Generally, only monsters
with an Advancement entry of "By character class" receive NPC gear; other creatures adding character levels should be treated as monsters
of the appropriate CR and assigned treasure, not equipment.
Feat Acquisition and Ability Score Increases:
's total Hit Dice
, not its ECL, govern its acquisition of feats and ability score increases.
