What's so exciting about Mysterious Ring where you wait until level 11 to craft that slot? On a caster, you're probably better off with a Spinneret and a Feywild ring rather than trying to eek out 2% crit and 10 spellpower (only 2 spellpower delta compared to the Spinneret).
Thanks for the advice.
But sadly I don’t have Spinneret (slave is a long quest to grind) and fey (maybe waiting for a sale).
Instead of the Fey/Slave TR gear, I am doing more like Chrono/Ravenloft/Sand. I am having my electric arti life with Golden Greaves +Mysterious Ring for electric.
So I can craft something I am missing in the gear set like False Life/Persuasion/ins PRR on the ring.
Well I commented what I craft, maybe not optimal
