Choose backgrounds that fit with your character concept, or for skills proficiencies you really want.And don’t forget to apply them to your array!
Just try using a race with either Wisdom or Intelligence score bonuses. Hill dwarves are also good choices for clerics as are half-elves.
Use the variant human racial ability score bumps to increase Intelligence to 16 and Dexterity to 14 take War Caster for the free feat. If your DM allows variant human, use that option instead. Starting off as human will bump up all of your ability scores by 1.Having at least 12 Dexterity works well with medium armor. You want at least a 13 in both Intelligence and Wisdom for multiclassing. Use the standard array for ability scores to get the following: 15 Intelligence, 14 Wisdom, 13 Dexterity, 12 Constitution, 10 Strength, 8 Charisma.Cleric domains also automatically give some freebie prepared spells.
It’ll be up to you how to use your spell slots, though. Since you prepare spells for each class separately, you will have, on average, more spells at your disposal each day. Once you’ve multiclassed at level 2, you’ll have a total of at least seven cantrips. Multiclassing usually gives spellcasters a lot more cantrips than usual. They do damage, provide utility, and even buff characters. Cantrips are at-will spells that let you do magic without using spell slots. Now your wizard can also heal and buff using spells they don’t normally get!
A single level of cleric gives lets us prepare at least two spells from the cleric spell list. These proficiencies also free you up from having to learn the mage armor spell. This means that you’ll have about 16 to 19 Armor Class (AC) depending on your Dexterity and armor. Multiclassing into cleric gives our Clizard medium armor and shield proficiencies. For example, you have access to only 1st-level cleric spells while you’ll learn higher-level wizard spells as you level up. But, you’ll have to keep track of prepared spells for each class. There’s no change in the spell slots you’ll have access to because both wizards and clerics count the same towards slot progression. This build also gains access to medium armor and shield proficiency and features granted by a cleric domain. We exchange some of our wizard spell progression for access to healing and buffs from the cleric spell list.
