Monster Breeding - Runestones

Runestones are essential tools to create more advanced monster hybrids. There are six unique runestones in the game to customize the treatments of juvenile creatures.

Some of them can enhance existing resistance to fire, frost, or shock; others can tame wild beasts, heal abomination illness, or increase the litter size. The player needs to build Hatchling's Cabin and purchase runestones to be able to set up treatment.
