Growing up

Growing up is the process in which an NPC (non player character) such as a tame kitten turns into a larger version of itself (e.g a housecat). Monsters grow from killing monsters and receiving xp, from the effects of potions of gain level, or from wraith corpses.

Monsters will grow up as follows:

Baby dragons grow into dragons of the same type

Kittens grow into housecats and then into large cats

Little dogs grow into dogs and then into large dogs

Wolf cubs and winter wolf cubs grow into wolves and winter wolves

Naga hatchlings grow into nagas

hellhound pups grow into hellhounds

Liches grow to demiliches, master liches, and then into arch-liches

elves grow into elf-lords, then Elvenkings

gargoyles grow into winged gargoyles (Although some are born with wings, and hence hatch from winged gargoyle eggs)
