# Skilltrees You can think of skilltrees like classes for players (for example knight and archer). #### Skilltrees Within the pet-type-file you can create the **skilltree**. Each **skilltree** needs its own name, which means that you aren't allowed to create **2 or more** skilltrees with **the same name** in the same file. If you create more than one, only the first will be used. #### Level Within a skilltree you can specify from which levels the pet should get a new ability or rather when existing abilities should be updated. #### Skills Within the levels you can specify which ability will be learnd or should be updated. Any Ability has it's own custom option that can be set in the skilltrees. ### Inheritance **Skilltree**s are capable of inheritance which means if **skilltree** `a` inherits from **skilltree** `b`, **skilltree** `a` will have all the settings form **skilltree** `b` and in adition to the own settings. The inheritance of already inherted skills can be disabled by setting MyPet.Skilltree.InheritAlreadyInheritedSkills to `false`. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
