Planar

Spells Gained:
Planar Philosophers gain all conjuration spells at their lowest level to their formulae list

Mutagen effect:
A Planar Philosopher’s mutagen adapts their mind to the strange realities of other planes, but detaches their body. They gain their bonus to Wisdom, and penalty to Constitution.

At 5th level you begin to move in strange ways, subtly shifting through space. You gain +10ft movement speed, and +5ft to any other forms of movement you possess.

At 10th level your form can press through the folds of reality. While under your mutagen’s effect you may teleport as dimension door as a standard action up to 30ft away, you may do this up to 3 + Wisdom modifier times per day (Minimum 1).

At 15th level the mutagen stretches you across many planes. You and everything within 5ft of you are treated as if under the effects of ghost touch. In addition to ghosts this prevents abilities which rely on a creature shifting in and out of a given plane such as plane shift as you are treated as on the same plane regardless until they leave your aura.

At 20th level you begin to slip between planes easily, you may teleport now up to 60ft as a move action and may as a full round action cast plane shift on yourself only. While still under the effects of your mutagen you may stay on any plane safely, and are forced back to the plane you took the mutagen on once it expires.

Incense Lure (Sp):
At 3rd level the Philosopher learns to create and use a specialized incense that can lure a creature from the outer planes. In order to prepare this incense he must select a creature he can summon from a conjuration spell he can cast, as a part of his mutagen. When he uses his mutagen the incense is activated and if he summons the selected creature it appears with its type changed to aberration and having a number of evolution points equal to your wisdom modifier. These evolution points can be spent on any eidolon evolution, treating your summoner level as your Philosopher level – 2. You may not choose any evolution which has limited uses per day or grants spell like abilities.

Pocket Dimension (Su):
At 6th level you create a small container such as a flask, pocket, or tiny chest, anything that can be easily carried in one hand. This container holds an extra-dimensional space with a total volume of 2sqft per level and up to twice your heavy load of encumbrance for weight, while weighing effectively nothing itself. You may absorb any item into the container up to small size as a standard action, medium as a full round, and double for each size category larger, within 30ft. You cannot target creatures with this unless they are summoned creatures, such creatures must make a will save (DC 10 + Half you level + Intelligence modifier) or be absorbed into the pocket dimension. For one hour you may retrieve the creature, it treating you as its new summoner with a duration remaining as it had when it was absorbed. If this absorbs an eidolon every round both in the container and under your control it receives a will save (DC 10 + Half Philosopher level + Intelligence modifier) to break free and return to its master. If the container is broken treat it as replacing a wizard’s bonded object

Hammerspace (Su):
At 9th level you may draw items from your pocket dimension as a free action provided you can carry it in two hands. You may also draw a summoned creature from it as a move action.

Retreat (Su):
At 15th level your pocket dimension is made to comfortably accommodate you. It is now treated as a demiplane inside as the Create Demiplane spell. This plane is permanent and may only ever have the structure feature and one you select upon its creation. This extra effect can be changed once per day. Whenever you choose to enter your retreat you are absorbed into your container leaving it behind as the exit, though for all other creatures it acts as a mundane item (Though detects as magical). Entering or leaving the retreat is a full round action.

Notes for Planar philosophers:
Alturas doesn't have a planar system as most settings do, however it does have alternate dimensions which can work to the same effect. Mechanically the only ability that changes is the mutagen effect. Instead of only applying to plane shift it applies to any teleportation spell, effectively even once a creature teleports away until they physically move themselves 5ft or more they're treated as within 5ft of you. So if a creature Dimension Door's within 5ft of you 60ft away, you may still attack it until it moves 5ft through non teleporting means.
