SRD:Effective Character Level
From Dungeons and Dragons Wiki
- This material is not part of the SRD, and is added only for clarity.
What It Is
Your effective character level is the number used when calculating how many experience points you receive when defeating challenges, and how much experience you require to reach the next level.
How it is calculated
Effective character level is calculated by adding your total racial hit dice, class levels and Level Adjustment. Members of the standard races have an ECL that equals their character level.
