Krivis-Taoist combo is in a really bad spot right now so that’s not an option.
On Topic:
Don’t mix Priest3 with Diev3 ever, while it looks good on paper it’s not that great, they’re better in separated builds so you can use the other ranks to take things that benefits them.
If you want to keep the Priest you can go for:
Cleric2-Priest3-Chaplain-Miko-Taoist
Cleric2-Priest3-Chaplain-PD2
Those are the most common builds (there are other variants but to not make this so long we’ll go with the usual ones), first one is entirely a support build, it’s really good for ET and stuff, if you want you can ditch Chaplain and pick Miko at R6 leaving R7 open to either Oracle or PD1 for that status ailments removal, stats would be full SPR too.
The second one is somewhat of a support-semi dps one because of PD2, it’s very good to help clearing and it helps soloing a little bit more, stats would be full SPR too, you can also go with full INT and max Aspersion instead of Blessing but that would be a more solo build and doesn’t provide as good support as a full SPR one buff wise.
Now if you want to go the Diev route you can go this:
Cleric2-Diev3-Miko-PD2
This was the most common (and OP) build for Diev, it got nerfed since the combat patch but it’s not that bad, provides utility and DMG on it’s own, stats would be full INT for this one, Miko is heavily recommended for this build because of Clap which extends the duration of the statues.
