Thanks to your elf blood, you have superior vision in dark and dim conditions.
You have advantage on saving throws against being charmed, and magic can't put you to sleep.
You are in frequent contact with people in the segment of society that your chosen quarries move through. These people might be associated with the criminal underworld, the rough-and-tumble folk of the streets, or members of high society. This connection comes in the form of a contact in any city you visit, a person who provides information about the people and places of the local area.
You can inspire others through stirring words or music. To do so, you use a bonus action on your turn to choose one creature other than yourself within 60 feet of you who can hear you. That creature gains one Bardic Inspiration die, a d8.
Once within the next 10 minutes, the creature can roll the die and add the number rolled to one ability check, attack roll, or saving throw it makes. The creature can wait until after it rolls the d20 before deciding to use the Bardic Inspiration die, but must decide before the DM says whether the roll succeeds or fails. Once the Bardic Inspiration die is rolled, it is lost. A creature can have only one Bardic Inspiration die at a time.
You regain all of your expended uses of Bardic Inspiration when you finish a short or long rest.
You can use soothing music or oration to help revitalize your wounded allies during a short rest. If you or any friendly creatures who can hear your performance regain hit points by spending Hit Dice at the end of the short rest, each of those creatures regains an extra1d6hit points.
The extra hit points increase when you reach certain levels in this class: to 1d8 at 9th level, to 1d10 at 13th level, and to 1d12 at 17th level.
If a creature has a Bardic Inspiration die from you and casts a spell that restores hit points or deals damage, the creature can roll that die and choose a target affected by the spell. Add the number rolled as a bonus to the hit points regained or the damage dealt. The Bardic Inspiration die is then lost.
You are a master at saying the right thing at the right time. When you make a Charisma (Persuasion) or Charisma (Deception) check, you gain advantage proficiency bonus times per long rest.
You can spin words laced with magic that unsettle a creature and cause it to doubt itself. As a bonus action, you can expend one use of your Bardic Inspiration and choose one creature you can see within 60 feet of you.The creature must subtract 1d8 from the next saving throw it makes before the start of your next turn.
When you reduce a hostile creature to 0 hit points, you gain 12 temporary hit points.
When you make an ability check or a saving throw, you can use this feature to 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.
When you cast eldritch blast, add your Charisma modifier to the damage it deals on a hit.
You can now inscribe magical rituals in your Book of Shadows. Choose two 1st-level spells that have the ritual tag from any class's spell list. The spells needn't be from the same spell list. The spells appear in the book and don't count against the number of spells you know. With your Book of Shadows in hand, you can cast the chosen spells as rituals. You can't cast the spells except as rituals, unless you've learned them by some other means. You can also cast a warlock spell you know as a ritual if it has the ritual tag.
On your adventures, you can add other ritual spells to your Book of Shadows. When you find such a spell, you can add it to the book if the spell's level is equal to or less than half your warlock level (rounded up) and if you can spare the time to transcribe the spell. For each level of the spell, the transcription process takes 2 hours and costs 50 gp for the rare inks needed to inscribe it.
A new page appears in your Book of Shadows. With your permission, a creature can use its action to write its name on that page, which can contain a number of names equal to 4.
You can cast the sending spell, targeting a creature whose name is on the page, without using a spell slot and without using material components. To do so, you must write the message on the page. The target hears the message in their mind, and if the target replies, their message appears on the page, rather than in your mind. The writing disappears after 1 minute.
As an action, you can magically erase a name on the page by touching it.
You have learned techniques to enhance your attacks with certain kinds of spells, gaining the following benefits:
• When you cast a spell that requires you to make an attack roll, the spell's range is doubled.
• Your ranged spell attacks ignore half cover and three-quarters cover.
• You learn one cantrip that requires an attack roll. Choose the cantrip from the bard, cleric, druid, sorcerer, warlock, or wizard spell list. Your spellcasting ability for this cantrip depends on the spell list you chose from: Charisma for bard
