Your patron can communicate with you telepathically, and you can use an action to ask your patron a question. The patron answers with knowledge available to it, using whatever means it prefers.

As an action, you can restore all expended Pact Magic spell slots. Once you do so, you cannot use this feature again until you finish a long rest.

Make a ranged spell attack dealing 1d10 force damage, with extra damage from Agonizing Blast and the option to push the target 10 feet away with Repelling Blast.

Make up to four beams, directing each beam at the same target or different targets.

Grant yourself 26 temporary Hit Points when you reduce a hostile creature to 0 Hit Points or score a critical hit, or grant them to an ally within 30 feet.

Hurl a creature's spirit through the Lower Planes until the end of your next turn, dealing 8d10 psychic damage if it is not a Fiend when it returns.

You draw on an otherworldly patron to wield pact magic. You use Charisma as your spellcasting ability, and your spellcasting focus can be an arcane focus, a component pouch, or an item associated with your patron.

You gain one Eldritch Invocation. At higher levels you gain additional invocations, for a total of eight at level 20. Riola's invocations are Agonizing Blast, Armor of Shadows, Fiendish Vigor, Investment of the Chain Master, Repelling Blast, Lessons of the First Ones, Eldritch Mind, and Lifedrinker.

Once per long rest, you can perform a one-minute rite to regain expended Pact Magic spell slots.

You gain the Fiend patron subclass. Your patron is Vezrul, the Kindly Ember, a benevolent demon of the Abyss.

When you reduce a hostile creature to 0 Hit Points or score a critical hit against one, you gain temporary Hit Points equal to your Charisma modifier plus your Warlock level, 26 temporary Hit Points. You can choose to gain these temporary Hit Points immediately or grant them to a creature you can see within 30 feet.

You gain an Ability Score Improvement or another eligible feat. Riola's final ability scores already include all chosen improvements.

You can select additional Eldritch Invocations as shown by your warlock level. You can also replace an invocation whenever you gain a warlock level.

When you fail an ability check or saving throw, you can add 1d10 to the roll, potentially turning failure into success. Once used, you cannot use this feature again until a short or long rest.

After finishing a short or long rest, choose one damage type. You gain resistance to that type until you choose a different type with this feature. Fiendish Resilience cannot be used against force or psychic damage.

You gain Mystic Arcanum for a 6th-level spell. You can cast the chosen spell once without expending a spell slot, and you regain the ability to do so when you finish a long rest.

You gain Mystic Arcanum for a 7th-level spell. You can cast the chosen spell once without expending a spell slot, and you regain the ability to do so when you finish a long rest.

You gain Mystic Arcanum for an 8th-level spell. You can cast the chosen spell once without expending a spell slot, and you regain the ability to do so when you finish a long rest.

You gain Mystic Arcanum for a 9th-level spell. You can cast the chosen spell once without expending a spell slot, and you regain the ability to do so when you finish a long rest.

You gain an Epic Boon feat. Riola has taken Boon of Fate, allowing him to add or subtract 2d4 from a creature's attack roll, ability check, or saving throw within 60 feet after seeing the d20 roll, once per short or long rest.

You have spent your life in the service of a temple, learning sacred rites, religious customs, and the care of worshipers. You can usually secure modest food and shelter from a temple of your faith or an aligned religious institution, though you are expected to assist with simple religious duties in return.
