While this allows a character to gain access to the features of many classes at the same time, it also risks a multiclass penalty.
Many class features rely on the number of class levels, so there's a possibility that a multiclassed character could be spread too thin to be effective in all areas.
You start with your Base Class and then somewhere on your Next Level you decide to select a Different Class from your Base class; The character must still meet the requirements for that class (usually an alignment restriction for base classes, but more elaborate pre-requisites for prestige classes). The NEW class that you selected will be starting at Level 1 Class level.
- NO, You do NOT Skip the Class level of your initial Base class, when you continue on Leveling your original Base class, Nor the other Class you selected.
|Character / Race||C L A S S||Class Level|
|Level 1||your Original Base Class Level||1|
|Level 2||your Original Base Class Level||2|
|Level 3||2nd Class Level selected||1|
|Level 4||your Original Base Class Level||3|
|Level 5||3rd Class Level selected||1|
|Level 6||your Original Base Class Level||4|
|Level 7||3rd Class Level selected||2|
|Level 8||2nd Class Level selected||2|
|Level 9||2nd Class Level selected||3|
|Level 10||2nd Class Level selected||4|
|Level 11||3rd Class Level selected||3|
|Level 12||your Original Base Class Level||5|
Well, You get the Idea.
- You will also suffer Multiclass penalty for such decisions, but there are Exceptions.
