It is a game modification that incorporates the old gameboy games. Players choose a starting pokemon, gain experience, and catch new pokemon. As players level up their pokemon, that pokemon's skill will become more deadly. If a pokemon manages to evolve into another pokemon, the new pokemon will have a new skill plus its predecessors. However, players are limited to using a single pokemon at one time, but can have a 'party' that they can switch with on the fly with the command /go. Some pokemon are designated as 'global' pokemon, and as long as they are in your party, their skill will work as well.
-There is also a unique item system that has been developed where server owners can manage and create new items based on a simple file (items.cfg). This item system can be utilized to create an almost endless amount of items that you can imagine.
-Additionally with PokeMod there is a 'PokeRank' system, where players gain points every time they level up their pokemon. This can become competitive as there are defaulted 11 types of pokeranks, starting from Pokemon Finatic and working to Legendary Guru. On top of these individual ranks, there is also a server rank. If you have the top pokerank in the entire server, you will be designated as the Pokemon Master, and the next four highest are part of the Elite Four.
-Not commonly used in PokeMod is the 'Safari' mode. This mode allows players to choose any pokemon that the server has enabled for Safari mode. There is no experience gain and players are able to change pokemon freely. Pokemon can either be disabled, admin only, or set to a level.
