There are currently 23 selectable races and 2 non-selectable races available on KotL. All races except humans have the potential to grow into something stronger over time. Once all of your character's ten stat categories are maxed out, (strength, dex, wisdom, etc) you can choose to transform (charisma is a static stat, and does not need to be maxed to reach next evolution). 

You will for a time be weaker after doing this. Your stats will fall below what they were, so you will have to raise them back up through training. However, you will now have better racial resistances and fewer weaknesses while having higher statistical maximums than before. There are sometimes chances of a random 'extra' that occurs to a person when they transform that will not occur to all, like perhaps extra strong scales that help armor class. The following is a list of the races and their evolutions.

¹- The two evolutions of Kalcin are auto aggressive creatures. This means that any mob (within a specific set range) that you encounter, will attack you. This makes for harder leveling, and stat maxes. Please consider this only if you are familiar with the mud.

²- The two evolutions of Lizardman are auto agressive creatures. This means that any mob (within a specific set range) that you encounter, will attack you. This makes for harder leveling, and stat maxes. Please consider this only if you are familiar with the mud.

³- Humans are a non-evolutionizing race on KotL. The stats are higher then a normal first evolution, but over all, other races will stat out higher on the higher evolutions.
