Intimidating Strike

You have honed your melee weapon technique into a terrifying display of precision and dominance. When you strike with perfect accuracy, enemies witness the brutality and hesitate to challenge you further.

Weapon Mastery Requirement.
You can only activate this feature if you have Weapon Mastery with the melee weapon you used to score the critical hit.

Assassination Threshold.
When you score a critical hit with a melee weapon attack against a living humanoid, you can activate this feature if the target meets both of the following conditions:

• The target has 95 or fewer maximum hit points.
• The target is at or below the following percentage of its hit point maximum:
– Level 4–7: 25% or lower
– Level 8–11: 30% or lower
– Level 12–15: 40% or lower
– Level 16+: 50% or lower

If both conditions are met, the target is reduced to 0 hit points and automatically triggers Horrifying Sight.

If the target does not meet these conditions, or has more than 95 maximum hit points, it instead takes the normal damage of your critical hit and still triggers Horrifying Sight.

This feature only affects living humanoids.

Horrifying Sight. (only triggered by Assassination Threshold aka the original target)
When this feature activates, your weapon becomes coated in the target’s blood and emits a faint, unsettling glow visible only to creatures affected by this ability.

You choose a number of hostile creatures up to your character level + your proficiency bonus within 15 feet of you that can see you. The original target does not count toward this limit.

If the original target survives the attack, it automatically fails its saving throw.

Each chosen creature must make a Wisdom saving throw with a DC equal to 8 + your proficiency bonus + your Strength or Dexterity modifier (chosen when you gain this feat).

On a failed save, the creature suffers the following effects for 1d4 turns:
• You have advantage on all attack rolls against it.
• It has disadvantage on all attack rolls against you.

On a successful save, the creature becomes immune to this ability for 24 hours.

If the original target was reduced to 0 hit points by this feature, all affected creatures make the saving throw with disadvantage.

Uses.
You can activate this feature twice per long rest.
