Tarkanan Ruffian

When the ruffian casts Witch Bolt, roll 1d8. On an even number, the ruffian gains a number of Temporary Hit Points equal to the number rolled. On an odd number, one creature of the ruffian's choice within 30 feet of it takes Force damage equal to the number rolled; if no other creatures are in range, it takes the damage.

The ruffian casts one of the following spells, requiring no Material components and using Constitution as the spellcasting ability (spell save DC 12, +4 to hit with spell attacks):

At will: Thaumaturgy

1/day: Witch Bolt

Melee or Ranged Attack Roll: +4, reach 5 ft. or range 20/60 ft. Hit: 6 (1d8 + 2) Piercing damage.
