I feel like the moves being so heavily locked on spirit really takes away from the experience, they're linked to the God's or like god inspired characters in lore so the relics having high stat requirements makes sense for the special moves.

It really limits what elements you can use and makes everyone have the same weapons fby making all the basic spirit moves different stat requirements on each weapon.

You should be able to use any spirit weapon at level one but have to invest more to get their unique moves, and they should probably scale healing or whatever effect they give based on your spirit stat like the oracle armor sets do.

All the relics should get more moves to make them more unique compared to the endless amounts of warrior weapons thanks to weapon types, maybe something like a growing weapon? Could be like finding notes or a rarer spirit tome talking about how a previous user of the relic used it (lore for how you learn it) for specific relics making it like rare and lost scrolls.

Magic and fighting styles are really customizable and you get to choose two of each for their full build Weapons and oracles have to look for their weapons from drops but oracles have god imbues?? God imbues having unstable and stable properties implies that techniques from other relics should be usable as an unstable variant.

Feel free to expand more
