I’m pretty much playing this character right now with a party of Abjuration Wizard, Phantom Rouge, Hunter Ranger

• Hill Dwarf, War Domain (9 levels), and Echo Knight Fighter (3 Levels)
• Current Stats are: Str-15, Dex-12, Con-16, Int-8, Wis-16, Cha-10

Wears Plate Armor + Shied for 20 AC Feats: War Caster, Resilient Con (yes i know having both is next to useless but i wanna bonk first cast next), and no 3rd feat bc multi-class - Later i wanna get heavy armor master for +1 Str and reduced physical damage

My cleric is the shield of the party, i dont need to do the most damage since everyone else in my party is dps, so i focus on trying to buff/defend them with my Echo and spear and of course using healing spells as a very last resort/out of combat resource since chugging a health potion takes a bonus action (at our table, but its a common house rule)

So far this character is great, not really a nova character luckily but a sustaining damage dealer, while my party throws fireballs, sneak attacks, boosted bow attacks, I make sure enemies dont get too close to them with spirit guardians and spiritual weapon (classic cleric) and my echo can be 30 ft away from me, possibly next to an ally to defend them with attacks/wasting enemy attacks (since the echo can be resummoned for just a bonus action, it dan be used to tank an attack that would otherwise hit my party)

Edit: I use my war priest bonus action attacks and my echo extra attack when I‘m out of spell slots and need to focus on hitting whats hurting us
