Part of it depends on how you want to play. Personally, I love playing a CC/buffer/debuffer version of cleric. Outside of the spells mentioned by others, here are some of my favourites:

Sanctuary — I can’t tell you how many times I’ve saved an ally/myself from death because of this spell.

Shield of Faith— cast this on your melee meat shield and let them do what they do best.

Faerie Fire — IMO one of the most underrated spells in the game.

Guidance — One of the best cantrips for people who like to role-play in towns and villages. Cast it on yourself or your bard and make haggling with townsfolk a whole lot easier.

Those are all pretty low level spells. And FWIW If you’re a fan of buffing/debuffing/CC than Twilight Cleric is fucking incredible. It’s basically broken if you know what you’re doing.

Anytime! And FWIW we’ve used cotton balls in the past and they worked perfectly. Even looked like fog of war lol. You could even spray paint them black/grey if you want to go the extra mile.

I was wondering this too. My first thought was cotton balls.
