If you did go with the triple threat I suggested it would net you all of these abilities (eventually and in whatever order you actually mutliclass)
- Bard
- 2nd level bard spells; 7 spells known; 3 bard cantrips (including vicious mockery very fey themed!
)
- d6 Song of Rest
- Bardic Inspiration d6 = Charisma Modifier
- Jack of All trades: +1/2 proficiency to any skill you're not proficient with
- 1 ASI/Feat
- Expertise in 2 skills
- 2 Glamour abilities: Mantle of Inspiration (grant 5 temp hp to people), Enthralling Performance (charm with a performance)
- Druid
- 7th level druid spells; 4 druid cantrips (start with 2) which should include guidance!
- Wildshape: 2/Short or Long rest 7 hours per change, up to CR 1 beasts not limited by movement mode (so any beast)
- 3 ASI/Feats
- All the Dream Druid Abilities: Balm of the Summer Court (2nd), Hearth of Moonlight & Shadow (6th), Hidden Paths (10th), Walker in Dreams (14th)
- Warlock
- 2x 1st level Spell Slots, 3 1st level warlock spells known, 2 Warlock cantrips (could get minor illusion here or from bard)
- 2 Invocations which for your build would probably want to include 2 of these 4:
- Beguiling Influence: proficiency in deception & persuasion skills
- Mask of many faces: disguise self at will without a spell slot
- Misty Vision: silent image at will without a spell slot
- Thief of Fates: bane once with a spell slot, but good way to mess with them. Steal their luck/fate.
- Archfey - Fey Presence: 1/short or long rest charm or frighten creatures in a 10' cube on a failed save.
Man.. now I want to play this build
The only questions are: 1) which class to start with first 2) how to alternate or level them up. 3) What Background to take for other proficiencies
They're all d8 hit points, so you have consistency there.
- Skills; Bard gives you 3 of any skills while the other two give you 2 skills from their list.
- Saves: Bard = Dex/Cha, Druid = Int/Wis, Warlock = Wis/Cha
- Weapons: Bard = Simple + hand crossbow, longsword, shortsword, rapier, Druid = very specific list, Warlock = Simple
- Armor: Bard = light, Druid = light, medium, & shields, Warlock = light
- Tools: Bard = 3 instruments, Druid = Herbalism kit, Warlock = none
Multiclass into you gain these proficienies:
- Bard: one instrument, one skill (any), light armor (everyone has this so it's not a consideration)
- Druid: light armor, medium armor, shields
- Warlock: light armor, simple weapons.
Background can start you well and then let you mutliclass later into that thing more fully. So you could start as a Druid with the Entertainer background, then gain one more skill and one more instrument when you mutliclass into Bard. You could start as a Bard with the Outlander background who was the skald of a druid circle, left to enjoy the world, then comes back to embrace their circle and fey roots, etc.
I'd probably start as Druid and mutliclass into bard and warlock at later levels.
Practically speaking 3 classes might be too much to actually enjoy the class abilities, so think about what of the above you'd enjoy the most and focus on those first, and so on.
