All-Father's Spawn

• You have disadvantage on Wisdom (Perception) checks that rely on sight.
• You gain truesight out to a range of 60 feet.
• You are wracked with pain, subtracting 1d4 from all ability checks.
• Your Strength score becomes 29.

Clairvoyant. When you finish a long rest, roll three d20s and record the numbers rolled. You can replace any attack roll, saving throw, or ability check made by you or a creature that you can see with one of these foretelling rolls. You must choose to do so before the roll, and you can replace a roll in this way only once per turn. Each foretelling roll can be used only once. When you finish a long rest, you lose any unused foretelling rolls. 

Furthermore, you cannot be flanked, and hidden creatures gain no advantage on attack rolls against you.

Orcish Critical. When you score a critical hit with this magic weapon, you can roll two additional weapon damage dice when determining the additional damage. When you deal this additional damage to a Huge or smaller creature, you can push it up to 15 feet in any direction.

Wrath of the One-Eyed. As an action, you can choose to strike the ground with earth-shattering intent. A shockwave of roiling ground and thunderous energy erupts forth from you in a 60-foot cone, forcing each creature caught in the area to make a Constitution saving throw. The DC is equal to your Strength score. On a failed save, a creature takes bludgeoning damage equal to 6d12 + your Strength modifier and is knocked prone. On a successful save, a creature takes half as much damage and is not knocked prone.

Any nonmagical objects within the same area are dealt maximum damage by this magical effect. In addition, the ground in that area becomes difficult terrain until cleared. Each 5-foot-square portion of the area requires at least 1 minute to clear by hand.

Once you use this action, you can't use it again until you finish a long rest, unless you expend 1d6 + 4 hit dice to use it again. If this action reduces you to 0 hit dice, you die.

Destroying the Club. The club is destroyed if it is pierced by six of Corellon's arrows.

Proficiency with a Greatclub allows you to add your proficiency bonus to the attack roll for any attack you make with it.
