I'm in the middle of an "Oops All Clerics" playthrough. Highly recommend. I have Light, Life, Tempest, and War. War is probably the weakest of the bunch but she's good for holding concentration buffs. Throw on bless and Phalar Aluve Sing and you'll never lose concentration on anything.

All of my ability checks get guidance and advantage.

This party is stupidly OP. The shadow cursed lands were a cakewalk, and I steamrolled Cazador without really trying. Hasted Tempest cleric pumps out obscene amounts of damage.

Light has access to fireball, wall of fire, and their Chanel divinity is a nuclear bomb with a huge range.

Life can almost bring a completely dead party back to full health.

And the Chanel divinities restore after a short rest, so I can deal with three moderate fights and maybe even a boss before I need a long rest.

I think Cleric might be my favorite class.
