In Everquest most races have their own languages. If a players is talking while having for example the tier’dal (Dark elf language) active, only other dark elfs or people who have learned that language will understand what hes saying. Character that havent yet learned the tier’dal language will only get a bunch of gibberish letters in their chatbox. But all classes thankfully knows the common language so everyone can understand each other. Aside from roleplay reasons there are quite a few charm items in the game that will increase in power as your language skills increase, like the Tainted Heartstone , Charm of Exotic Speech, Petrified Mushroom Stalk, and Flawed Defiant Charm .
