I don't generally create builds of this level because I will probably not get to play them, but this one is crazy powerful. Without further ado, lets start with the build.
Race
For this build we can choose any race, the gimmick of this build will not be affected by stats or most race features. For the example I'll use a dragonborn for no reason in particular.
Stats
For our stats we will use standard array. Our build includes starting at cleric and multiclassing into bard so we need wisdom and charisma of at least 13. I'll focus charisma and constitution as our main stats:
| Str | Dex | Con | Int | Wis | Cha |
|---|---|---|---|---|---|
| 14 | 8 | 14 | 10 | 13 | 16 |
Progression
Level 1 (Life Cleric 1):
Our first level will be as a life cleric, which gives us Disciple of Life which will make us a fantastic healer from the get go.
Disciple of Life: Starting at 1st level, your healing spells are more effective. Whenever you use a spell of 1st level or higher to restore hit points to a creature, the creature regains additional hit points equal to 2 + the spell's level.
Level 2-7 (Life Cleric 1 / Lore Bard 6):
In level 2 you have to multiclass to bard and in level 4 take the lore bard college.Until level 6 you are free to build your character as you want! I personally recommend taking advantage of your Heavy Armor Proficiency (from Life Cleric 1).
In level 7 is when you become the greatest healer to have ever lived. As a level 6 Lore Bard you get access to Additional Magical Secrets:
Additional Magical Secrets: At 6th level, you learn two Spells of your choice from any class. A spell you choose must be of a level you can cast, as shown on the Bard table, or a cantrip.The chosen Spells count as Bard Spells for you but don’t count against the number of Bard Spells you know.
For our build to be complete, one of our spells will be the Paladin Spell: Aura of Vitality. This spell is concentration and for 1 minute we can heal 2d6 to a creature 30 feet from us as a bonus action each turn. With Disciple of Life this becomes 2d6 + 5 which is 12 healing average.
12 healing is the same as the average of casting healing word at level 2 with +4 charisma. The difference is that you do it every turn, and you can cast spells that are not cantrips in the same turn! All of this for a 3th level spell slot (and by this point we have 3 of them).
Result
This is a very versatile build as it only requires 13 on wisdom and charisma and is not affected by ability modifiers. You can be a very potent healer while doing other bard things in your turns. As bards are so versatile you can build your bard in any way you want!
The only drawback is that you won't have 4th level spells, but you still have a 4th level spell slot you can use to upcast your spells.
