Bard / WarlockMulticlass Build Guide — D&D 5e

The bard’s spell list is wide but shallow on damage. You can charm, heal and control, but when it comes to raw ranged output you are stuck with Vicious Mockery (1d4, the lowest damage cantrip in the game). Two warlock levels fix that permanently: Eldritch Blast plus Agonizing Blast gives you 1d10 + Charisma force damage at 120 feet, scaling with character level, and both halves run on the Charisma you already maximised.

Pact Magic slots recharge on a short rest, the same rhythm as your Bardic Inspiration (from 5th level onward). That means every short rest refills two warlock slots for emergency casting plus your Inspiration pool — a sustained output loop that pure bards cannot match. Devil’s Sight paired with the Darkness spell creates a bubble of advantage on your attacks and disadvantage on theirs, which turns a College of Whispers bard into a terrifying infiltrator and duelist.

The cost is two to three levels of bard progression delayed. That pushes Magical Secrets at Bard 10 out to character level 12 or 13. If Magical Secrets is your primary reason to play bard, time the dip carefully — take it before level 7 or after level 10, never straddling the Secrets breakpoint.

Ability priority: CHA → DEX → CON — Charisma powers Eldritch Blast, bard spellcasting, and Bardic Inspiration. Dexterity for AC in light armour. Constitution for concentration and hit points.
