I'm playing a tempest cleric(5e) currently lvl 3, cutom liniage - resilient con
8 str, 14 dex, 16 con, 17wis, 10 int, 8 cha
I have magic innitiate wizard - background (find familiar, booming blade, shape water)

I plan to pick up telekinetic to raise Wis and help with double spirit guardians damage/booming blade activation

At lvl6 there is another chanel divinity which is mandatory pick up for tempest cleric

What do i do past this point? do i just cleric all the way? coz call lightning upcasts so well that i could not find a spell to beat it even on other spell lists

Is there anything to multiclass to that allows me to pick up shield/other worthy non cleric spells?
Any other ideas where to take this?
