I think with the rings variation is important so here are some of my suggested addition

Specters Ring: while under effect of transience the wearer can phase through blocks and fly but can't interact with blocks anymore

Wild magic Amulette:
While casting a spell there is a chance that another spell you know triggers which obviously won't ever be able to retrigger the Amulette. Use with caution

Ring of Terraforming: you can now break and place blocks using mine from afar but also use it like a building wand and break or fill rows of blocks at a distance

Amullet of the traveler
When walking on the bridge of summend blocks they extend using Mana of the used wand to allow you to walk over infinite distances.

Ring of the falling leaf
Triggers glide from a wand of you hotbar whenever you are falling

Amullet of the rapid caster
Projectile spells have a chance of triggering twice when used creating a quick firing sequence

Miners Glory
Uses light spells in dark spots and triggers divination near ores both from your wands.

Ring of claustrophobia
Triggers a close range spell when attacked at close range. Chance gets higher the more attackers surround you

Amullet of disembodiement
Triggers possession on the mob that brings you down to under 3 hearts and uses mind trick on all other mobs in a certain range. (certain chance)

And I wanted to suggest one more spell:
Befriendment affected creatures become your pet and act like dogs.(Attack when you hit sth or sth hits you, follow you Teleport after a certain distance if you don't make them sit)
