Demiplane Owner

You have gained mastery over the manipulation of extradimensional spaces and have become the owner of your own demiplane, a pocket dimension of your creation. This feat enhances your abilities to control and utilize your demiplane to your advantage.

Benefits:

1. Demiplane Mastery: You gain the ability to cast the spell Demiplane once without expending a spell slot. You can only use this ability once, and you regain the ability to do so after completing a long rest.

2. Secure Storage: Your demiplane becomes a secure storage space for your belongings. It has a maximum capacity of 10 cubic feet per character level. You can access your demiplane at any time, as long as you are on the same plane of existence. Retrieving or storing an item in your demiplane requires a bonus action.

3. Personal Sanctum: You can customize your demiplane to create a personal sanctum. You can spend 8 hours and expend 1,000 gold pieces worth of materials to create a comfortable living space within your demiplane. This space can include furniture, amenities, and other comforts you desire. Your personal sanctum provides the following benefits:

   • You and up to eight creatures you choose can benefit from a long rest within your personal sanctum, completing the rest in half the usual time.
   • While within your personal sanctum, you and your chosen creatures gain a +2 bonus to saving throws against spells and other magical effects.

4. Plane Shift Attunement: Your time spent as the owner of a demiplane has attuned you to the nature of planar travel. You gain the following benefits:

   • You can cast the spell Plane Shift once without expending a spell slot. You can only use this ability once, and you regain the ability to do so after completing a long rest.
   • When you cast Plane Shift, you do not need a tuning fork or any other costly material component for the spell.

5. Dimensional Refuge: Your mastery over demiplanes grants you additional protection. Once per long rest, as a reaction when you are hit by an attack, you can use your reaction to instantly teleport yourself to your demiplane. You disappear from your current location and reappear within your demiplane. This ability cannot be used if you are already inside your demiplane or if you are incapacitated.
