This is ring is a bit special because this ring contain 19 spell of my choosing, this spells are according to me, is essential on your BG3 playthrough, the problem is, most of this spells are locked behind classes, and thus this ring is created.

And yes because this ring come from modder specialised in cheating, some of the spells are changed to be more... well cheaty. For example :
Feather Fall : changed from 10 turns to until long rest.
Dancing Lights : changed from 10 turns to 20 turns.
Sleep : now have 1000 hp to spent since you cannot upscale if you're not a spell casting class.

And 2 of my favorite :
Chain Lightning : The radius are now 50m wide with 20d20 damage, the "jumping" projectile count now increased to 20.
Power Word Kill : Now the minimum requirement of target HP is 1000.
