Cashaan the Red

Magic Resistance. Cashaan has advantage on saving throws against spells and other magical effects.

Legendary Resistance (3x/day). When Cashaan fails a saving throw, he may choose to succeed.

Blood Pact. Cashaan can perform a ritual that takes 1 hour to bind a willing creature in a blood pact. Once bound in this way, Cashaan has influence over the bonded creature. The pact can only be ended with the agreement of both Cashaan and the bonded creature.

Endless Bond. Cashaan may cast touch spells on any bonded creature from any distance.

Blood Leash(1x/short rest). As a magic action, Cashaan can form a supernatural bond with a creature of which he shares a blood pact. The bond lasts for 1 hour or until concentration is broken. While the bond is in effect, Cashaan can use an action to learn the target's approximate distance and direction from him as well as it's current hit points and any conditions affecting it. Alternatively, he may use an action to attempt to connect with the target's senses. The target must make a DC 25 Constitution saving throw. On a successful save the bond ends, on a failure Cashaan can choose to see and hear through the target's senses for 7 minutes.

Blood Puppet(1x/short rest). As a magic action, Cashaan can force a bonded creature to make a DC 25 wisdom saving throw or become charmed by him for the duration. An unconscious creature automatically fails the saving throw and is not incapacitated when he is in control of it. On the affected creature's turn, Cashaan can command it to move up to half it's speed and use it's action to interact with an object, make a single attack, cast a spell, or do nothing. An affected creature may make a new saving throw at the end of each of its turns, ending the effect on a success. The effect lasts 1 minute or until concentration is broken.

Sanguine Siphon (7x/Short Rest).  As a magic action, Cashaan can siphon life from a bonded creature within 120ft. The creature makes a DC 25 Constitution saving throw, taking 10d8 damage on a failure and half that on a success. Cashaan then regains hit points equal to the damage dealt.

Vital Control. Cashaan may perform a 10 minute ritual to curse a bonded creature. At the end of the ritual, Cashaan may choose to either reduce the creature's constitution score by 1d8 to minimum Con score of 1, or to remove a creature's spellcasting ability. The effect can be reversed by Cashaan by repeating the ritual. A creature may only be effected by one curse at a time. This effect can only be removed by a wish spell.
