Executioner

As an executioner, you have learned the anatomy of many sentient creatures to ensure a quick, painless kill. You enforce the law and bring your wrath upon those who disobey it. Since most humanoids have a similar anatomy, you are an expert at slashing your opponent's head clean off.

The Beheader

When you take this oath at 3rd level, you gain the ability to turn one of your melee weapons that deals slashing damage into "The Beheader".

When attacking with "The Beheader", you receive a +2 bonus to attack rolls.

Additionally, when rolling a critical hit (natural 20) with "The Beheader" against a creature whose size is medium or smaller, roll a d4. If the result is a 3 or a 4, you chop the target's head clean off and kill it instantly (assuming the creature has a head and requires it to survive; this is for the DM to decide). If "The Beheader" has the Two-Handed, Heavy or Versatile properties, it can also behead creatures whose size is large. For Versatile weapons, the bonus only applies when you attack with both hands and is invalid when you only use one hand.

When attacking with "The Beheader", you have an advantage against frightened creatures and you need not to roll a d4 when making a critical hit against prone creatures, you instantly behead them.

You can transfer the "Beheader" title to any weapon that meets the criteria mentioned above during a short or long rest.

Oath Spells

You gain oath spells at the paladin levels listed.

Executioner Spells

Aura of Doom

Starting at 7th level, you and friendly creatures within 10 feet of you can’t be frightened while you are conscious.

At 18th level, the range of this aura increases to 30 feet.

Weak Spot

Beginning at 15th level, you may spend an action to roll a wisdom (perception) against the target's charisma (deception) check and having the higher overall result means victory. If you are the victor, you manage to learn the target's species and you have an advantage in attack and damage rolls against the target and all other creatures of its race until the battle ends. You must complete a short rest before using this again.

Execute

At 20th level, you may pick one hostile creature at will. You inform the creature of the imminent death that will be caused to them by your hands. The creature is now frightened of you and you gain advantages in attack and damage rolls against it. You may behead the creature even if it is out of your size-range, and if it is in your size range, you do not need to roll a d4 in order to behead it and you kill it instantly with a critical hit. You must then complete a long rest in order to use this again.
