Oh, also keep aware of which spells are Concentration. Half-casters get such a small list of spells that you have to be careful curating what spells you take. When we did the tabletop Curse of Strahd game I took 3 total concentration spells on my ranger: Hunter's Mark, Healing Spirit, and Protection from Good and Evil.
If it had been post Tasha's I probably would have taken a Smite spell instead of Hunter's Mark since I played a Strength-based melee Ranger (Defense fighting style)
You can only run one Concentration spell at a time (baring some third party feats we won't see in BG3 because they're Third Party material). So if your cleric casts Bless then you'll want to think carefully before casting Hold Person because that's another Concentration spell and casting it will cause you to drop Bless.
