Too tired to check if anyone’s already suggested it, but I think Chaplain/Exorcist/Inquisitor is a good build for dealing damage as a cleric. Not exactly the best self-heals, but Exo and Chaplain should give you enough SPR to have a decent healing stat.
There’s quite a few things you can bop regular mobs with in this build, such as the ever reliable God Smash and Rubric. You also have Breaking Wheel + Visible Talent and Cappella + Judgment + Rubric to really tear into stronger enemies.
On the defensive side, you have… almost nothing. With only your basic cleric support skills and Engkrateia to help keep you alive, you can’t always afford to take risks that classes like Plague Doctor and Priest can. On the plus side, Chaplain has some pretty reliable super armor, so you can at least ignore a knockback or knockdown that would have gotten you in trouble.
