Tempus

Tempus was the greater god of war in the Faerûnian pantheon The dogma of the Lord of Battles was primarily concerned with honorable combat, forbidding cowardice and encouraging the use of force of arms to settle disputes. You've entered a bargain with him to sow chaos in the mortal realm and to strike down all who oppose you.

Servant of Chaos

At 1st level, you acquire the training necessary to effectively arm yourself for battle. You gain proficiency with medium armor, shields, and martial weapons.

The influence of your patron also allows you to mystically channel your will through a particular weapon. Whenever you finish a long rest, you can touch one weapon that you are proficient with and that lacks the two-handed property. When you attack with that weapon, you can use your Charisma modifier, instead of Strength or Dexterity, for the attack and damage rolls. This benefit lasts until you finish a long rest. If you later gain the Pact of the Blade feature, this benefit extends to every pact weapon you conjure with that feature, no matter the weapon's type.

Also, you have a pool of d6s that you spend to heal yourself or your comrades in combat. The number of dice in the pool equals 1 + your warlock level.

As a bonus action, you can heal one creature you can see within 60 feet of you, spending dice from the pool. The maximum number of dice you can spend at once equals your Charisma modifier (minimum of one die). Roll the dice you spend, add them together, and restore a number of hit points equal to the total.

Your pool regains all expended dice when you finish a long rest.

Stalwart Steward

Starting at 6th level, you can curse the soul of a person you slay, temporarily binding it in your service. When you slay a humanoid, you can cause its spirit to rise from its corpse as a specter. When the specter appears, it gains temporary hit points equal to half your warlock level. Roll initiative for the specter, which has its own turns. It obeys your verbal commands, and it gains a special bonus to its attack rolls equal to your Charisma modifier (minimum of +0).

The specter remains in your service until the end of your next long rest, at which point it vanishes to the afterlife.

Once you bind a specter with this feature, you can't use the feature again until you finish a long rest.

Bolster the Reserves

Starting at 10th level, you gain temporary hit points whenever you finish a short or long rest. These temporary hit points equal your warlock level + your Charisma modifier. Additionally, choose up to five creatures you can see at the end of the rest. Those creatures each gain temporary hit points equal to half your warlock level + your Charisma modifier.

Otherworldly Retreat

Starting at 14th level, you gain the ability to sequester yourself and your allies in a pocket dimension of your creation.

By performing a special ritual over the course of 5 minutes, you shift yourself and up to five willing creatures you can see to the pocket dimension. You and those creatures gain the benefits of a short rest while sequestered on the pocket dimension. You then return to the spaces you all occupied when you used this ability, with no time having passed in the world.

During this short rest, you and the creatures you sequester can make use of any options available during a rest that affect only you and the creatures you sequester.

Once you use this ability, you cannot use it again until you complete a long rest.
