Monsters

Information
Monsters are entities that can spawn in different locations at different levels and rarities. With each level, their health, damage, defense, souls dropped, and other abilities can increase. For example, a level 1 normal rarity bat could have 9 health points and maybe one ability, but a level 7 would have much more life, and probably a few abilities.

Monsters also have hit points (HP) and attack (atk) base stat bonuses which range from 1 to an unknown maximum which is only achievable by breeding. In the wild however monsters' base stat bonuses are capped at 50. The current known highest value is 53.

If you are looking for Bosses, they have their own page.

Rarity
There are 5 rarities, represented by a prefix added to name (except normal) and change in color as well as higher HP and more bonus parameters:
