The Gatekeeper

The many planes of the universe are bound to each other through the Ethereal Plane. Whether it was an invention of your own, a gift from an extraplanar entity, or a relic of a lost civilization, you have come across a magical key that can access this bridge.

Gatekeeper’s Key

1st-level Gatekeeper Feature

At 1st level, you find a magical key that seems to fit every lock. You gain proficiency in Thieves’ Tools and may use your Gatekeeper’s Key to make lockpicking checks. When you make a lockpicking check with your Gatekeeper’s Key, you may use your Charisma modifier instead of your Dexterity modifier.

Unlock the Ethereal

1st-level Gatekeeper Feature

At 1st level, you have learned to use the Gatekeeper’s Key to open a door through the Ethereal Plane as a quick shortcut. As a bonus action on your turn, you may teleport up to 30 feet to an unoccupied space you can see. This ability can be used a number of times equal to your Charisma modifier. You regain expended uses at the end of a long rest.

Finding Familiars

As a note, your Planar Gateway feature has some familiar options which are capable of casting spells a certain number of times and recharge on rests. Casting Find Familiar again and summoning the same creature does not regain any charges on these spells. Your character must complete the associated rest to allow the familiar to regain those spells. However, summoning a different familiar, through your Key of the Five Realms feature or from the Elemental Chaos, will provide a new set of spells that have not been expended.

Creatures marked with * are homebrew creatures.

Planar Gateway

6th-level Gatekeeper Feature

At 6th level, you have learned to use the Gatekeeper’s Key to open gateways into dangerous planes, allowing for the entities that reside there to spill into the plane you occupy. At the end of a long rest, you may attune your Gatekeeper’s Key to one of the following planes: The Elemental Chaos, The Feywilds, The Abyss, The Seven Heavens, or The Outer Planes. Until the end of your next long rest, all spells associated with the chosen plane are considered known Warlock spells for you.

Additionally, you may expend uses of this ability to cast these spells without expending a spell slot. This ability has a number of uses equal to your proficiency bonus. You may cast spells associated with the plane the key is attuned to by expending a number of uses equal to the spell’s level. You regain expended uses at the end of a long rest.

If you chose the Pact of the Chain as your Pact Boon, familiars you create from using the spells granted by this ability act as though they were a familiar created through your Pact Boon.

Arcane Door

10th-level Gatekeeper Feature

At 10th level, you have learned to travel quickly between frequently visited places. By performing a day-long ritual, you create an arcane door that allows for instantaneous travel across long distances. The door is 10 feet wide and 15 feet tall. You may create a number of these doors equal to your proficiency bonus. If you attempt to create a door after already reaching the maximum number of doors you can create, you must choose on of the doors you’ve already created. That door will disappear and cannot be used again.

As an action, you may use your Gatekeeper’s Key to open a door you created with this ability that is within 5 feet of you. Select one other door you’ve created that is on the same plane of existence as you. A portal forms between those two locations and remains there for the next minute, or until you use your bonus action to close and lock one of the doors. Any creature may walk through the portal as part of their movement while it is open, instantly transporting them to the other side.

Additionally, you may cast Plane Shift as a 10-day ritual once per long rest.
