This uncommon specialist is a student of magic that relies on the manipulation of space, time and dimension. The dimensionalist is familiar with all kinds of extradimensional pockets, planes and sources of power. While other wizards can make use of these dimensions, the dimensionalist has a much clearer understanding of what he is doing and why when he casts spells of this school. Non-Euclidean geometry and planar relationships are difficult material, even for a wizard; a character must have an Intelligence/Reason of 16 or better to grasp the more esoteric concepts required to master this kind of magic.
The school of dimensional magic includes spells such as rope trick, dimension door, distance distortion, and maze. Dimensional magic is opposed by the schools of enchantment/charm and necromancy, since these philosophies have nothing to do with extraplanar studies or spells.
The dimensional specialist gains the normal advantages for specialization as described earlier in this chapter. In addition, at eighth-level, the dimensionalist gains the power to disappear by stepping into a pocket dimension once per day. While in the pocket dimension, he is detectable only by spells that can discern dimensional openings and is immune to any attack, but he also has no way of knowing what’s happening in the place he left until he chooses to step back into the real world. The dimensionalist may remain for up to one hour before he is forced to exit and can take any actions he desires (sleeping, reading, drinking a potion, or so on) while inside. Note that the pocket dimension’s point of exit is always the exact same place the dimensionalist entered the dimension. Also, no spells that would allow the dimensionalist to leave the pocket without first reentering the real world can function in the extradimensional place, including teleport, dimension door, shadow walk, and similar enchantments. At 11th-level, the dimensionalist may bring one other human-sized creature or an object weighing less than 500 pounds with him. At 14th-level, he may bring up to five companions or an object weighing 1,500 pounds.
The dimensionalist is a very unusual wizard, with access to some of the strangest spells in the game. A high-level dimensionalist can be a confounding opponent, calling on rarely seen powers to trap or misdirect his enemies. Dimensionalists have few attack spells, but excel in avoiding trouble or circumventing obstacles.
