The Devout and the Dead: a guide to Clerics

[Thankee Sai]

One thing you might change is to mark Destructive Wrath in the Tempest Domain as sky blue, since it can quite substantially increase your damage output (Booming Blade at L14 with Divine Strike can do 32 thunder damage outright), Channel Divinity is recharged after a short rest which is commonly taken after small encounters when you may only have 2 turns anyways, and it lets you implement it after you know an attack has hit or missed (you use it instead of rolling damage dice).

Also for anyone wanting to get Booming Blade and/or Shocking Grasp that is interested in multiclassing with the Rogue, you can take the Arcane Trickster archetype at the 3rd level giving you Mage Hand, two wizard cantrips of your choice, and a few useful 1st level spells (one of your choice, one enchantment spell and one illusion).
