The Witch Knight

Some people throughout the world whether they meant to or not have been touched by some kind of eldritch power and are now forever marked. These individuals are now able to channel such power through this mark and can harness this power for themselves. Many Witch Knights feel a call to the wilds defending small folk from horrors that mere hunter or town guard can handle. Some Witch Knights accompany rangers or work alongside druid groves to weed out corruption or perhaps hunting beasts through city streets in the dead of night while the unaware sleep

Your eldritch abilities have manifested and can now be unleashed upon your foes. When you take this archetype at 3rd level you gain the following benefits:

Eldritch brand: As a bonus action you can mark a creature with an eldritch brand. This brand lasts for an hour and can be dismissed before then with no action required. You have advantage on wisdom (perception) and wisdom (survival) checks needed to track the branded creature. Additionally when you hit a branded creature with an attack you can deal an additional 1D6 necrotic damage. The damage increases when you reach certain levels in this class. The damage increases to 1D8 at 7th level, 1D10 at 10th level, 1D12 at 15th level and 3D6 at 18th level. You can do this a number of times equal to your proficiency bonus and gain all uses back when you finish a long rest.

 

Magical connection: You touch one weapon you're proficient with and form a bond with that weapon. While bonded this weapon is considered magical for the purposes of overcoming magical resistances and immunities.

You may also do this to one weapon at a time and can be bonded with over the course of a short or long rest.
