I mean, that's how it is.

Its why nature magic is the most versalite magic there is. Holy people have a range of life and death magic plus their god's domain. Wizards can't heal at all. Warlocks, sorcerers, bards, they only retain so much even with diverse choices.

Nature magic may not as be an effective healer as a holy person, or as destructive as a wizard, but we can fulfill the needs of our people because we adapt.
