Traits
Undead Creation
A Vengeant Knight is both a Construct and an Undead.

Aversion of fire
A Vengeant Knight takes triple damage from weapon attacks with a fire element added to it.

Savage Creation
A Vengeant Knight does not align with any creature, it will attack anything it perceives.

Vengeance Counter
When hit with a fire damage attack or spell, a Vengeant Knight gains a Vengeance Counter (Max 3) Vengeant Knights consume Vengeance Counters when they hit with their Axe attacks, turning them into critical hits.

Brutal Critical
A Vengeance Knight can roll one additional weapon damage die when determining the extra damage for a critical hit with a melee attack.


Actions
Multiattack
The Vengeant Knight makes three melee weapon attacks with his axes

Axes
+7 to hit, 1d12 slashing + 1d8 fire +7

Burning Vengeance (Once per day)
All creatures within 15 feet of the Vengeance Knight must make a DC15 Wisdom saving throw, on a failed save they must make another DC15 Wisdom save every time they try to attack a creature that is not the Vengeant Knight, if they fail this save they must attack the Vengeant Knight, additionally their weapons ignite with magical fire for 8 hours, adding 1d8 fire damage to their weapon attacks, on a successful save creatures are unaffected, but their weapons still ignite.

Weapons affected by Burning Vengeance can be sheathed safely, but once drawn again will burst into flame, a dispel magic spell ends this effect early.

Usage Notes
Vengeant Knights are single minded engines of destruction, created when the enraged soul of a warrior is bound to an iron armor by a process of flame and spell, as such, a Vengeant Knight will attack even it's creator, Necromancers or Wizards reckless enough to employ a Vengeant Knight usually stay far away from their creation, lest the magical axes find no other target than them.

Combat
A Vengeant Knight charges towards the closest creature it can perceive and attacks until it is dead, in combat, their vengeant nature leads them to attack whichever creature causes them the most damage, and if they can't reach that creature, they will carve a path to them.

Single Minded
A Vengeant Knight does not reason or strategize, if it kills an opponent with one strike, it will almost always attack the corpse until given reason to switch targets.

Looting
A Vengeant Knight's armor is in no state to be used, it's too big, and generally of poor quality, the only protection it offers the undead soul inside is that of heavy bulk, it's magical axes often melt into the gauntlets, when your players try to loot the axes, describe one as unusable and beyond salvage, while another might be repaired.
