That's a quite cool combination.
One thing I like doing in act 2 is combining blood of Lathander, coruscation ring and luminous armour on a cleric and then cast spirit guardians and walk right through the enemies.
Blood of Lathander will blind all fiends and undead and illuminates you. The other two items will apply radiating orbs to the enemies. So they will have disadvantage on their attacks and recive a stacking penalty on their attack roll. If enemies are somewhat close to each other this penalty can easiely reach -8 or higher on your first turn. This means they are almost guaranteed to fail any attack rolls, which allows you to freely walk around and hit everyone with spirit guardians without needing to disengage or having to worry about losing concentration.
Another nice thing is combining hellfire hand crossbow (inflict burning when attacking from hide or invisibility) and firestoker (bonus damage against burning targets).
