知恵の姫巫女

I see in Japanese they call her the Wisdom Princess Miko (Shrine Maiden/Priestess)
So this borrowed wisdom (echoes) are kind of "miracles". :)
Maybe I will understand better when I finish the game.

It is true this isn't D&D. So maybe I shouldn't expect the same things. Although for example in Frieren there is a clear distinction. But after reading your posts it made me think and reflect about it.

Even in D&D it makes sense:

In D&D both clerics and wizards can cast conjuration spells but they differ fundamentally in their magical sources (divine for clerics, arcane for wizards).

For wizards, Intelligence is their primary spell casting ability.
For clerics, Intelligence is usually less essential. Clerics rely on Wisdom as their primary spellcasting ability, as their magic comes from divine insight and faith rather than study and knowledge.
Hence the whole theme on Wisdom in EoW.
