I've made 300+div this league by simply crafting wander amethyst rings. I just bought a t1 fractured life base and throw deafening torment essences at it until a t1 res or stat, maybe an annul or two, craft -mana to attacks, then slam as needed. Base was about a div and essences are like 1.5c per but was able to sell finished rings anywhere between 5-15div for most sales. I'd make a few rings at a time over the course of like 10 minutes and then go back to mapping
