Pretty simple - just a small QOL change. Items with spirit gems or any other parts which are emitting the effects of vitality should share your spirit color.
Lets pick vitality amulet for example: Currently it has blue gem socketed in it and emits blue effects. Why not make it so merciful paladins get golden gem which emits golden effects? Red gem and red effects for ruthless paladin and so on for the rest of variations of spirit energy colors.
I feel like this change would add more variety in already existing drip for vitality enjoyers and point out their character’s traits even more.
Besides, lets not forget that we already have something similiar - arcanium and fstyles items, their look is different depending on your magics or fstyles, so why don’t we have something similiar for vitality? I suggest only color change, no stat changes.
Could just use a similar system to the Arcanium items, make it so theres technically types to each of these items, and it changes upon attempting to equip it if it does not match yours.
i gave it a low effort rating because it’s just a really simple suggestion, even if it is good. honestly i think it’s super arbitrary compared to the other two, mainly when it comes to tiny qol stuff
