Diev 1 carves a statue that lowers skills’ cd by 20% and slow enemies down, it’s always a useful statue to carve.
Diev 2 brings some extra DPS, an aoe to silence enemies, and Diev 3 brings a statue that gives you immunity for some time.
Since those effects are good and don’t depend on any stats (except for the Owls to deal damages), you can mix Diev with any build, which is why it is that popular.
Diev 1 would be mostly a filler with the need of -20% cd if some of the classes you pick have skills with high cooldowns.
If you have high INT and Priest’ Exorcise you could go Chaplain to make it even better, but it’s a 60s cd combo.
I wouldn’t go Pardoner with SPR that isn’t too high, it won’t be worth it as much.
You could probably go Chaplain and Miko at R5 and R6 for some extra DPS, since your classes so far, and Kabba, lack damages.
You can also switch Chaplain for Cleric 2 if you want extra heals. It brings safety, but it isn’t a total necessity.
