Action Name. Enter the description for your action.

Sword of Wounding. Melee Weapon Attack : +5 to hit, reach 5 ft., one target. Hit: 10 (2d6 + 3) slashing damage.  The target must also make a constitution saving throw DC 15 or take another 2d4 necrotic damage. Another 2d4 of necrotic damage is dealt every subsequent turn until the creature makes the DC 15 Constitution save or is healed by another creature. Even when healed to eliminate the continuous wounding, the necrotic damage dealt doesn't heal more than the slashing damage originally dealt.

Eldritch Blast. Ranged Spell Attack: +6 to hit, range 120 ft., 2 beams. Hit:  (1d10 + 5) force damage.

Hellish Rebuke. Once per long rest. After a creature damages you, you point your finger towards them and they are surrounded by hellish flames. They must make a Dexterity saving throw DC 14, upon a fail they take 2d10 fire damage or half as much on a successful one.

Transform. If the creature is below 60% of its total HP, it can transform and assume its true form (Ascended Cambion). The creature will maintain its current HP at the time of the transformation, but all its abilities and traits will be changed to that of an Ascended Cambion.
