This mod adds .INI settings to change the level requirement for passive tames.
This is a complete default(vanilla) preset u can customize to your liking,
you can just use the entries you need or copy the whole section.
Not every passive tame is added, like the Astrodelphis or other not yet released creatures in ASA.
