I wonder if arcane healing can replace divine healing or divine one is stronger. Players ask me why the realms need gods at all, and due to ky lack of experience I just say that divine magic gives acess to the healing services that are really usefull so gods have aome use

1)
We know from existing spells and recorded usages of spellfire that arcane magic can indeed heal, but divine magic does it at lower spell levels and at less cost, so divine magic is specialized for healing.
And the Realms need gods because some mortals in the. 2)
…Realms believe the Realms needs gods.
It's like having clocks and calendars. Can we live without them? Yes, but some of us have decided we need them in our lives, so we have them.#Realmslore
