Personally the darkmoon card promises at 850 ilvl is amazing in terms of regen. It averages out at about 1150 mana saved per spell and with the static int trinket, and is better then the mythic cocoon, in that you don’t have to stop healing works passively. If you don’t need mana regen Thrumming Gossamer is going to be bis especially at 850 ilvl. Not only does it give us huge static int it also gives us a decent amount of mastery which is our top stat for progression. The third trinket I would have would be Concave reflecting lens from Glazer in vault of the wardens. Gives a huge amount of static crit which is our third best stat closely behind mastery. Also the equip effect is pretty nice especially on AoE fights, our niche.
