Lesson Streak

At 1st level, you benefit from maintaining a streak. as a Bonus Action, you can place a Streak on a creature you can see within 30 feet. The Streak starts at zero. Once per turn, when you hit the creature with an attack, the Streak increases by +1, up to a maximum equal to your Intelligence modifier (minimum of 1). On subsequent turns, you have a bonus to your attack rolls and damage rolls made against this creature equal to your Streak number. 

The Streak resets to zero when you place it on another creature, or if you have not attacked the chosen creature since the start of your previous turn.  

Language Lessons

Lingos, as a sign of good faith in entering a pact with them, has granted you the knowledge of 2 additional languages of your choosing. 

Heart Refill

At 6th level, your patron grants you power to recover lost health from its "hearts". as a reaction when you take damage, you can regain hit points equal to 1d10+ your warlock level.

once you use this feature, you cannot use it again until you complete a short or long rest. 

Language Barrier

Starting at 10th level, your mind has been filled with the knowledge of multiple languages, making it a steel trap, in more ways than one. If a creature attempts to read your mind, it must succeed an intelligence saving throw against your spell save DC or take 3d6 psychic damage. you also have resistance to psychic damage and you have advantage on intelligence saving throws.

Lingos has also granted you the knowledge of 2 more languages of your choosing, and has taught you how to create codes and cyphers. 

Lingos Strike

At 14th level, you are charged by Lingos  with reminding creatures of their all knowingness and power. As an action or as part of an attack action, you choose a creature you can see within 60 feet. for the next minute, you can use a bonus action to teleport to an unoccupied space within 10 feet of the target. Each time you teleport, you have advantage on your next attack roll made against it until the end of your turn. 

Each time you teleport, you can also choose to frighten the target. the Target must make a Wisdom saving throw against your spell save DC or it becomes frightened until the start of your next turn. 

you must complete a long rest before you can use this feature again.
