OK so when Revived rogue released I really liked the idea from an RP perspective. My DM and i decided that my Revived rogue would ave no memories and not know he was revived. 
The idea being that a Deity (i dont know who yet) has revived me for some purpose. at level 4 i will multi class into death cleric and get some info into my past. thats as much as i know. 
So here is the deal. im trying to decide what class to really focus on. the 2 play extremely well together allowing me the versatility of using spells and still using my sneak attack. 
Since my cantrips only care about max level i was thinking i might just take 2 levels in cleric but that renders my actual spells pretty pointless however with the Reaper skill my cantrips are kinda bread and butter. Ideas? 

Personally i like the 12/8 split. I don't know which rogue subclass you were thinking but arcane trickster allows 1/3 of your rogue levels count towards spells slot levels. which let you up cast spells like spirit guardians to deal a bunch of damage even when it's not your turn. You could also look into being a grave cleric which makes sense to me as you were dead.

Edit: I should have mentioned 12 rogue/ 8 cleric.

my rogue subclass is the new Revived rogue. ill look into that split. 
The main advantage to being a revived rogue is the ability bolts from the grave. after using your cunning action you use a spell attack and deal your sneak attack damage as long as you havnt used it that turn. 

Yep see that now, it even says it right there in the title.

I would still look at the 12/8 split it adds ASI, but also look at a 14R/ 6C split It gives you blind fighting and 2 uses of your channel divinity. 

That's actually a really cool combination that I can't believe I hadn't thought about until I saw your post.

the versatility has been great and the rp flavor is pretty savage. being able to stabilize a party member and sneak attack a target in the same turn while having a range of 70 movement has been awesome.
