Dimensional Anchor

When you cast this spell you must choose whether to Create a portal, Change a portal or Destroy a portal. The casting time is different for each option, as is the material component amount required. Please see the Casting Cost section at the bottom of each option.

Create a Portal

You conjure a portal anywhere you can see within range. The portal can be as small as 1 foot on a side or in diameter to as large as 10 feet on a side or in diameter. The portal must be linked to another location the caster has been to and provides a two-way semi-permanent passage between those points. If the caster wishes to keep the portal up, they must supply it with a continuous supply of materials used to cast it. Otherwise, it will only remain in this realm for a total of 5 minutes.

When you create the portal a red beam of lightning fires from your hand and in a storm of fire, rips apart the fabric between dimensions. You can limit what can pass through in a generic sense. You cannot decide, for example, that creatures of Evil alignment are blocked or that only Elves may pass through, or only yourself. You can however block air, water, or other elements, or even inanimate objects from passing through. 

Portals created by this spell are immune to Dispel Magic, Antimagic Field and similar such effects unless the opposing party knows this spell as well.

Casting Cost: this option takes 1 hour to cast and requires a material component of 12 pounds of crystals or an amount of life force ripped from the player worth 1/20th of the user's lifespan, which is then consumed by the spell.

Change a Portal

Choose a portal you have previously created by this spell that is within 30 ft of you. You remake the portal, as if using the Create a Portal option.

Casting Cost: this option takes 10 minutes to cast and requires a material component of 2 pounds of crystals or an amount of life force equal to ripped from the caster worth 3 years of time which is consumed by the spell.

Destroy a Portal

Choose a portal previously created by this spell that is within 10 ft of you. The portal is destroyed and vanishes with a loud crack leaving a burnt marking on whatever surface was closest.

Casting Cost: this option takes an action and does not require any material components.
