Carnage

Target a point that you can see within range. You invoke dark forces to create a wave of bloodlust in all biological creatures within 30 feet of that point, these must suceed a Charisma Saving throw. On a failed save, they become charmed and enter a frenzied state of violence for the duration, gaining the following effects:

• Affected creatures gain advantage on all weapon attacks
• All attacks against affected creatures have advantage
• Whenever an affected creature reduces another creature to 0 hit points, they gain 5 tempoary hitpoints.
• While an affected creature has more than half of its maximum hit points, it gainst resistance to non-magical bludgeoning, piercing and slashing damage.
• Affected creatures must use their action each turn to attack the nearest creature they can see. If no creatures are within range, they must move towards the nearest creature. If multiple creatures are at the same distance, they chose their target randomly. If no creatures are within sight, all effects ends on the affected creature.

Every minute affected creatures may repeat the original saving throw to end the effect early. If they reduced another creature to 0 hitpoints during the past minute, they make the save with disadvantage. A creature who succeeds on a save against this spell becomes immune to its effects for 24 hours.
