Why Fiend Patron?

Playing a Gnome Fiend Patron Warlock lets you pair the fiery explosive power of the Lower Planes with the innate magical defenses of a Gnome. As a "Blaster," your main goal is to deal massive damage from a distance using fire spells. When you reduce an enemy to zero hit points, your Dark One's Blessing feature immediately grants you temporary hit points. This makes you surprisingly durable for a squishy spellcaster, keeping you safe on the battlefield.

Your defensive capabilities are further boosted by the Gnome's natural traits. Gnomish Cunning gives you advantage on Intelligence, Wisdom, and Charisma saving throws against magic, meaning you roll twice and take the higher result. If a nasty spell does manage to slip through your defenses, you can use Dark One's Own Luck at level 6 to add a 1d10 roll to your failed saving throw, making you nearly impossible for enemy spellcasters to shut down.

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.

Pro Tips

Use your Gnome Darkvision to spot enemies in pitch-black rooms, letting you target them first and safely trigger Dark One's Blessing.

Rely on Gnomish Cunning for mental magic saves, saving your Dark One's Own Luck for physical Strength or Dexterity saving throws.

Focus your high-damage fire spells on weakened targets to guarantee the final blow, constantly refreshing your temporary hit points from your patron.

Change your active resistance from Fiendish Resilience after scouting ahead to match the damage type of the enemies you expect to fight next.

Frequently Asked Questions

Is Fiend Patron a good subclass for Gnome Warlock?

Yes, it is an excellent combination. Gnome Warlocks often lack high physical hit points, but the Fiend's Dark One's Blessing solves this by granting temporary health every time you defeat an enemy. Combined with Gnomish Cunning protecting your mind against hostile spells, you become a highly resilient magical artillery piece that can survive threats that would easily defeat other spellcasters.

What makes Fiend Patron different from other Warlock subclasses?

The Fiend Patron specializes in pure offensive fire damage and personal survivability. Unlike utility-focused patrons, the Fiend gives you access to classic area-of-effect spells like Fireball. It rewards an aggressive playstyle by granting you temporary hit points when you secure kills, and eventually lets you banish foes temporarily to another plane using Hurl Through Hell.
