Why Fiend Patron?

Warlocks who make pacts with fiends are master "Blasters"—spellcasters specializing in high-damage, explosive area-of-effect spells. While traditional spellcasters are notoriously fragile, choosing a Goliath adds incredible physical durability. Your Giant Ancestry (specifically using your reaction to reduce incoming damage) ensures you stay standing even when caught in the crossfire of your own chaotic spells.

This defensive synergy gets even better when paired with your level 3 subclass feature, Dark One's Blessing. Whenever you reduce a hostile creature to zero hit points, you gain temporary hit points. Together, these traits turn you into a self-sustaining turret who gains a shield of health with every enemy you incinerate.

Since your primary stat is Charisma (CHA), you will be casting powerful spells from a safe distance, but traits like Powerful Build and Large Form ensure you can easily shove threats away or escape tight spots if enemies manage to close the distance.

Fiend Patron Features

Dark One's Blessing

Level 3

When you reduce a hostile creature to 0 hit points, you gain temporary hit points equal to your Charisma modifier + your warlock level (minimum of 1).

Fiend Spells

Level 3

You gain additional spells that count as warlock spells for you: Burning Hands, Command (level 1); Blindness/Deafness, Scorching Ray (level 3); Fireball, Stinking Cloud (level 5); Fire Shield, Wall of Fire (level 7); Flame Strike, Hallow (level 9).

Dark One's Own Luck

Level 6

When you make an ability check or saving throw, you can add a d10 to your roll. You can do so after seeing the initial roll but before any of the roll's effects occur. Once you use this feature, you can't use it again until you finish a short or long rest.

Fiendish Resilience

Level 10

When you finish a short or long rest, you can choose one damage type. You gain resistance to that damage type until you choose a different one with this feature. Damage from magical weapons or silver weapons ignores this resistance.

Hurl Through Hell

Level 14

When you hit a creature with an attack, you can instantly transport the target through the Lower Planes. The creature disappears and hurtles through a nightmarish landscape. At the end of your next turn, the target returns to the space it previously occupied (or the nearest unoccupied space). If the target is not a fiend, it takes 10d10 psychic damage as it reels from its experience. Once you use this feature, you can't use it again until you finish a long rest.

Frequently Asked Questions

Is Fiend Patron a good subclass for Goliath Warlock?

Yes, it is an excellent choice for players who want a highly durable spellcaster. Goliath's innate damage reduction from Giant Ancestry perfectly covers the typical weakness of a Blaster Warlock. When combined with the temporary hit points from Dark One's Blessing, you become one of the hardest-to-kill spellcasters in D&D, allowing you to cast high-impact spells without fear.

What makes Fiend Patron different from other Warlock subclasses?

The Fiend Patron specializes in pure offensive destruction and personal survivability. Unlike utility-focused patrons, the Fiend grants access to classic, heavy-hitting fire spells. It is designed to reward aggressive play; features like Dark One's Blessing and Hurl Through Hell ensure that the more enemies you defeat, the safer and more powerful you become on the battlefield.
