Skill

Skills () are abilities gained from Racial Levels/Class Levels.
== Background ==
In the game, skills can be broadly divided into two types: Skills that can be activated at will, and Passive Skills () that are always in effect. Basically, they do not consume MP and can be used a set number of times, and the number of uses recovers after a one day or a set amount of time has passed. There are exceptions, such as Magic Strengthening Skills used in combination with Tier Magic, which consume additional MP.
Also, Demi-Human Species and Heteromorphic Species can gain Monster Abilities () as their Racial Level is raised.Overlord Volume 01 Chapter 2: Floor Guardians Human Species cannot obtain them because they do not have Racial Level, but the game's established theory is that the more Classes you take and the more diverse skills you gain, the stronger you become. However, the base stats of the Heteromorphic Species are extremely high, which makes their powerful skills even more mighty.Overlord First Half Chapter 60: Settings
In the New World, there are skills just like in YGGDRASIL, but the specifications may be different from those in the game. Also, the new world has skills called "Martial Arts," that did not exist in YGGDRASIL. Martial Arts are warrior skills exclusive to the local people, and currently YGGDRASIL players and NPCs cannot learn them.

The strength of the undead created depends on their race, such as dragons and zombies. Any race can be turned into a zombie or skeleton, except for slimes. Slimes are treated as an exception to this because they do not have a skeleton. In other words, slime zombies do not exist. This is common to both Yggdrasil and the world after the transfer.
