Oni's Destruction

Oni's Malice

3rd-level Path of the Oni feature
Starting at third level, you can use your action to create a mystical weapon in your empty hand,
formed using the powers of the Oni. You can choose the appearance of the weapon each time you
create it.
The weapon is a simple melee weapon which deals 1d8 bludgeoning damage and you are proficient
with it while you wield it. This weapon counts as magical for the purpose of overcoming resistance
and immunity to nonmagical attacks and damage.
Your weapon disappears if it is more than 5 feet away from you for 1 minute or more. It also
disappears if you use this feature again, if you dismiss the weapon (no action required), or if you die.
You can transform one simple melee magic weapon into your weapon by performing a special ritual
while you hold the weapon. You perform the ritual over the course of 1 hour, which can be done
during a short rest. You can then dismiss the weapon, shunting it into an extradimensional space,
and it appears whenever you create your weapon thereafter. You can’t affect an artifact or a
sentient weapon in this way. The weapon ceases being your weapon if you die, if you perform the 1-
hour ritual on a different weapon, or if you use a 1-hour ritual to break your bond to it. The weapon
appears at your feet if it is in the extradimensional space when the bond breaks.

Oni’s Flame

3rd-level Path of the Oni feature
As an action, you can slam your mystical weapon into the ground to cause a burst of flame. All
creatures within 5 feet of you are blasted by a blood-red demonic flame. All creatures within the
blast must make a Dexterity saving throw equal to 8 + your proficiency bonus + your Constitution
modifier. Each creature takes 3d8 fire damage or half as much on a successful save.
This damage increases by a further 1d8 at 6th level, 10th level and 14th level.
You can use this feature once per short rest.

Touch of Corruption

With the touch of your hand at your will, you can rot or rust items. As an action, you may touch a
target creature, who must make a Constitution saving throw equal to 8 + your proficiency bonus + your
Constitution modifier or be poisoned for 1 minute. At the end of each of its turns, the target can
make a Constitution saving throw. On a success, the condition on the target ends and is immune to
this feature for 24 hours.
You can use this feature a number of times equal to your proficiency bonus, and you regain all
expended uses when you finish a long rest.
You also have advantage on saving throws against poison, and you have resistance against poison
damage. You can also speak Abyssal, or another language if Abyssal is already known.

Gaseous Defence

10th-level Path of the Oni Feature

are grappled or knocked prone you can instead turn to a misty cloud and can immediately move up
to 15 feet into an unoccupied space. Once you have completed this movement, you are no longer
grappled or prone and revert back to your normal form. You can use this feature a number of times
equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.
