Raise Obelisk

9th-level transmutation

Casting Time: 8 hours

Range: 90 ft. (100-foot radius sphere)

Components: V, S, M* (enough currency or gems worth 10,000 gp, which the spell consumes)

Duration: Until dispelled or ended

You target a 20 ft. by 20 ft. square on the ground at a point you can see within range and begin chanting and weaving your hands. While chanting, a stone obelisk begins raising out of the ground covered in arcane symbols, and at the end of the casting time, this obelisk stands 100 feet tall. You then designate a password for this area to circumvent some of its wardings.

In a 100-foot radius sphere centered on the base of the obelisk, the area is now suffused with magic, emanating from the obelisk.

Within the area, creatures cannot magically teleport or travel in or out or use a portal to enter or leave the area, unless they speak the password beforehand, which you create. The area is warded against planar travel.

While you are within this area, you can use your action to cause the obelisk to unleash a bolt of lightning at a target creature also within the area. That creature must make a Dexterity saving throw. If they fail, they take 4d10 lightning damage, or half on a success.

In addition, you can use your action to make a target creature within the area make a Charisma saving throw. On a failure, the creature is teleported to outside of the area, ignoring the teleportation restrictions. That creature is then unable to enter the area of the spell for 7 days.

If a creature succeeds on this saving throw, they are immune to this effect for 24 hours.

You can only have one obelisk raised at one time. If you cast this spell again, the previous obelisk retreats back into the earth as the new one is raised.
