Pact of the Dwarven Lord

Your patron is a long dead Dwarven warrior. The pact formed with the blade depends on the soul contained within, but the blade will try to guide its wielder to complete the goals that align with its nature. 

Power of the Ancients

Your blade confers the benefit of keeping you aware of things around you that you are not aware of. While your pact weapon is on your person, you cannot be surprised, and you can choose to use your charisma ability score for attacks made with your weapon. 

Runes of the deep

As an action, you can choose a number up to your proficiency bonus of weapons or objects to imbue with a rune of empowerment. On a weapon, the rune causes the weapon to act as magical and grants a +1 to attack and damage. On an object,  the rune makes the item more durable and resistant to non magical damage. The runes last for 10 minutes and once used this feature cannot be used again until you take a short or long rest.  

One with Stone

As an action, you can meld into stone or earth to recover your energy. While in the stone you cannot see, but can feel the vibrations in the stone within 15 feet of you. When this ability ends, you are ejected from the stone to the nearest unoccupied space within 5 feet of the space you occupied. If there is no unoccupied space, you are pushed to the nearest space and take 1d6 force damage. This ability can only be used to take a short or long rest, and if ended early cannot be used again until you take a short or long rest. 

Call of the Dwarven Lord

As an action, you can target a group of humanoids within 60 feet up to your proficiency bonus to attempt to charm them. They must succeed on a wisdom saving throw or be charmed by you for the duration and think of you as their leader. The DC is your warlock save DC and Dwarves have disadvantage on the save. The charm ends after 1 hour or the ability is used to charm anyone else.
