Dragon Curse

Choose one of the following curses(all curses grant one elemental immunity, and dragon breath)

Draconic Wrath: Your dominant arm starts becoming covered in dragon scales(any dragon color) starting at the hand, on an attack action a player can slash with their dragon claw and deal 10d10 magical slashing damage to any creature in a 50ft line, and slicing anything else in half, following the path of their slash. Doing this will reduce your current health by 50%(player will fall unconscious when used at 1hp) this will also spread the dragon scales 2in(5cm) up the user’s arm. When the curse reaches the elbow, health reduction is dropped to 25%. At the shoulder no health is lost, and the curse either stops, or spreads to the player’s second arm.

Draconian Wisdom: The cursed player’s eyes change color(any dragon color) on a bonus action, the player can add 20 to all wisdom based checks for any given time, but after it ends their wisdom checks are reduced by 20 for that same time.

Draconic Avarice: The cursed gains colored scales along their jugular veins, this power can be activated at anytime ignoring turns to automatically succeed on any check, but automatically failing the next check. At  10th level you can succeed two checks before failing one, 3 at 15th level, and 4 at 20th level.
