I often wonder what you’re doing, because your experiences and mine are wildly different.
First, all slotting is in SOs, if you’re using DOs, I could see you having a problem.
You do have AM, right? I’d hope by level 22 you’d have 4 slots in it. 3 recharge SOs and an end mod SO.
RI and EF should have 1-2 end Redux slotted by now.
You’re lower level, so I’d assume you have no more than 3 slots in each attack. They should be 1 acc, 1 end redux, 1 damage.
if you’re below 27 on this toon, I don’t know how you have numina’s slotted, since that’s a 30+ set. You should have the panacea and miracle procs slotted in health by now though.
