Editing Blackstaff's Tome of Wizardry (section)

==School of Dimensionalism==
This the long-forgotten [[Dimensionalist]] brought back into 5th edition! These are specialist [[conjurer]]s who focus on manipulation dimensional barriers and portals, rather than summoning monsters.

At level 2, the Dimensionalist gains Proficiency in Arcana, doubles their Proficiency bonus for Intelligence checks relating to the [[plane]]s and other planar knowledge, and gets the feature '''Dimensional Pocket'''. This gives the wizard a personal [[Bag of Holding]] that nobody else can access, which contains an area of cubic feet equal to the wizard's Intelligence modifier. They can toss something into this pocket or withdraw it from the pocket as an action, and it can't be used to contain living creatures.

From level 6, once per short rest, the Dimensionalist can use an action to open a '''Dimensional Tear''', flooding a 15ft cone with raw elemental energy that does their choice of either Cold, Fire, Lightning, Thunder, Necrotic, Poison or Radiant damage (1d6+the dimensionalist's Wizard level) to anything caught in the area of effect. Targeted creatures are allowed to make a Dexterity save against this effect, halving the damage taken on a successful save.

From level 10, the Dimensionalist can use the ability '''Dimensional Slip''' at will. This is done as a Move action, and lets the Dimensionalist phase partially out of reality before moving; they count as moving through difficult terrain, but whilst moving in this way, they ignore all non-solid obstacles, creatures and terrain features as well as not provoking opportunity attacks. Once the Move action ends, the Dimensionalist fully materializes back in reality.

Finally, at level 14, the Dimensionalist gains a ''Demiplane Refuge'''; this is 20ft square cube demiplane whose gravity, lighting and atmosphere are controlled by the Dimensionalist, and which only they can access. They can enter or exit this demiplane as an action, and whilst they can't hide there forever (they still get hungry and thirsty), it can be use as a safe haven.
