The Fiend Arcane

In your pursuit of power and knowledge, you have made a pact with a fiend from the lower planes of existence, a being whose aims are evil, even if you strive against those aims. Fiends that would forge such a pact include the archdevil Mephistopheles, the infernal lord of wizards and arcane magic; or ultroloths and other lords of the yugoloths.

Intelligent Spellcasting

Instead of having charisma as your spell-casting ability for your warlock spells, you can instead use your intelligence to cast spells with. Additionally, any invocation which uses your charisma modifier to determine its effects can instead use your intelligence modifier.

Expanded Spell List

The Fiend Arcane lets you choose from an expanded list of spells when you learn a warlock spell. The following spells are added to the warlock spell list for you.

Fiend Expanded Spells

Spell Level	Spells
1st	burning hands, detect magic
2nd	flame blade, scorching ray
3rd	fireball, bestow curse
4th	fire shield, arcane eye
5th	immolation, hallow

Bonus Cantrips

At 1st level, you learn the fire bolt and shocking grasp cantrips. They count as warlock cantrips for you, but they don’t count against your number of cantrips known.

Arcane Flames

When you deal damage to a creature with fire bolt, that creature must succeed a Constitution saving throw against your spell save DC or catch on fire. Once on fire, the creature takes fire damage equal to your Intelligence modifier (minimum of 1) at the start of each of its turns until it uses its action to put out the flames

Potent Arcana

Starting at 6th level, your link to your patron increases the potency of your arcane spellcasting. When you roll damage for a spell, you can reroll a number of the damage dice up to your Intelligence modifier (minimum of 1). You must use the new rolls.

Arcane Resilience

Starting at 10th level, you can choose one damage type when you finish a short or long rest. 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.

Arcane Shroud

Starting at 14th level, when you are hit by an attack, you can use your reaction to deal force damage to the attacker if the attacker is within 60 feet of you. The damage equals half your warlock level.
