Okay, back to working on our PF1 witchwarper. Having already written up infinite worlds, let’s tackle the other key class features. We’ll still need to create a big set of paradigm shifts later, but this will form a strong framework on which to build those options, as well as skills, proficiencies, spellcasting, and so on.

Compound Sight (Su) – 3rd Level
You can sift through many realities, gaining understanding of a task by seeing it attempted dozens of different ways. Choose a skill. You gain a +1 insight bonus to checks using that skill. This bonus increases by +1 at 6th level and every 3 levels thereafter. You can change your chosen skill every time you gain a witchwarper level. At 9th level, you become more adept with your compound sight and can choose two skills to apply it to.

Alternate Outcome (Su) – 6th Level
You can use your grasp of other realities to swap an outcome in your current existence with that of a more favorable reality. As a reaction once per day, you can reroll one attack roll, saving throw, ability check, or skill check that you attempt. If the d20 on this reroll results in a 1-10 (the die shows a 1 through 10), add 10 to your total result. You must use the result of the reroll, even if it is worse than your original roll.
Alternatively, you can expend a use of this ability as a reaction to cause a critical hit against you or an ally within 100 feet to instead be a normal hit.
You gain one additional daily use of this ability at 12th level and again at 18th level.

Unfold Existences (Su) – 19th Level
You have nearly unlimited insight into all possible worlds and can pluck power from them as you deem necessary. Select five paradigms shifts you don’t know but whose prerequisites you meet. These paradigm shifts must not require your level to be higher than 8th. You can use the selected paradigm shifts a total number of times per day equal to your Charisma modifier.

Reality Stutter (Su) – 20th Level
Your force of will can infuse reality itself, changing key aspects of existence around you. You can spend a spell slot to use any paradigm shift you know. The spell slot must be of a spell level no less than half the minimum class level at which the paradigm shift can be selected.

This doesn’t take an action, but you must use this ability on your turn unless the paradigm shift can be used as a reaction. If the paradigm shift requires a reaction, you still can’t use it unless the stated trigger has occurred, but using it does not expend your reaction for the round. If the paradigm shift requires you to expend spell slots to use it, you must still spend those spell slots in addition to that spent to use this ability. You can use reality stutter only once per turn. You can use the unfold existences ability in conjunction with reality stutter; doing so expends a daily use of unfold existences as normal.

I have a Patreon. It helps me carve out the time needed to create these blog posts, and is a great way to let me know what kind of content you enjoy. If you’d like to see more Pathfinder 1st edition options (or more rules for other game systems, fiction, game industry essays, game design articles, worldbuilding tips, whatever!), try joining for just a few bucks and month and letting me know!

It has been suggested by some folks (including members of my Patron, who have a heavy influence on what I do for blog posts), that I should make a Pathfinder 1st edition version of the Sf “witchwarper” class. (Which will join the envoy, mystic, and solarian classes I have rewritten for PF1) So, let’s work on that.

Before I tackle any other questions, i want to make a run at the witchwarper’s core ability, infinite worlds. I may tweak this later, but for now a revision based on Pathfinder damage standards and rules terminology seems like a great start.

Infinite Worlds (Su) – 1st Level
As a standard action, you can create a bubble of altered reality, projecting elements of parallel existences into your current universe. You expend a witchwarper spell slot of 1st level or higher to create an environmental effect, such as summoning fog or thick vines from other realities, which lasts for a number of rounds equal to your class level unless specified otherwise. Alternatively, you can create an instantaneous effect, such a flash of fire from an explosion that occurred in a parallel universe. The particular effects depend on the level of the spell slot expended.

All effects created by infinite worlds use the following rules unless they say otherwise. They have a range of 100 feet + 10 feet per witchwarper level and affect a 10-foot-radius spread. If you create multiple effects with one use of infinite worlds, they all originate at the same point. If an effect calls for a saving throw, the DC is equal to 10 + the spell level expended to create the effect + your Charisma modifier. You can define the cause and appearance of infinite worlds however you wish (subject to GM approval), but the effects themselves are only quasi-real and have no effects beyond the game mechanics listed as options for this ability.

You can instead create multiple, milder effects in place of a single, more powerful effect. When you do this, you select two effects available to any version of this ability created by expending a lower-level spell slot than that you actually expend. For calculations based on spell level, use the level of the spell slot you expend.

For example, a 10th-level witchwarper could expend a 3rd‑level spell slot and select either a 3rd-level effect or any two abilities normally created by expending 1st- or 2nd-level spells. If you expend a spell slot 2 levels higher than the highest-level slot required for the effects you create, you can create 3 different effects. If you use a spell slot 3 levels higher, you can create four effects.

The environmental and instantaneous effects you can create by sacrificing a witchwarper spell slot of a given level are as follows:
1st (Environmental): You cause the affected area to become difficult terrain. This might mean that stone flooring becomes rough and uneven, a waterway is choked by roots and seaweed, or the air is flooded with floating strands of web-like filaments. You can affect a single movement type (normal movement, burrow, climb, fly, or swim) or any combination of those movement types. When you create difficult terrain in this way, it is considered magically altered terrain for the purposes of other effects.
1st (Instantaneous): You cause a bright flash of light to fill the area. Each creature within the area must succeed at a Fortitude saves or be dazzled for 1 round per witchwarper level. If a creature rolls a natural 1 on its saving throw (meaning the d20 shows a “1”), it is also blinded for 1 round.
2nd (Environmental): You cause a hazard that deals damage each round equal to the level of the spell slot expended, with a successful Fortitude save reducing the damage by half. A creature attempts this save when it first takes damage from this effect, and its result applies for the duration of the effect. You select the damage type each time you use this ability (acid, bludgeoning, cold, electricity, fire, piercing, slashing, or sonic).
2nd (Instantaneous): You cause a destabilizing event, such as a brief earthquake, a split-second reversal of gravity, or a blast of icy wind. Each creature within the area must succeed at a Reflex save or be knocked prone. If a creature rolls a natural 1 on its saving throw, it is also moved 5 feet per level of the spell slot expended in a direction of your choice.
3rd (Environmental): You cause the area to grant concealment against one sense—vision, scent, sound, or vibration.
3rd (Instantaneous): You cause a disorienting event, such as bursts of flashing colors and loud sounds, or rain falling upward in spirals. Each creature within the area must succeed at a Will save or take a -2 penalty to attack rolls for a number of rounds equal to the level of the spell expended. If a creature rolls a natural 1 on its saving throw, it is also staggered for 1 round.
4th (Environmental): You create a barrier, the entirety of which must be within the range and area of infinite worlds’ environmental effects. The barrier is a number of 5-foot cubes no greater than double the level of the spell slot expended. The cubes must each connect along one side with at least one other cube, have hardness equal to double the level of the spell slot expended, and each have HP equal to 5 × the level of spell expended. Barriers you could summon might include stone walls, slabs of ice, and so forth.
4th (Instantaneous): You create a burst of damage affecting everything in the area. You select the type of damage each time you use this ability (acid, bludgeoning, cold, electricity, fire, piercing, slashing, or sonic), and it deals 1d8 damage per level of the spell expended (Reflex half).
5th (Environmental): You make the air thicker or thinner, or fill it with toxic vapors. Each creature breathing the air must succeed at a Fortitude save or be sickened as long as it remains in the area. A creature attempts a single save when it is first exposed to the infinite worlds, which determines for the duration of the ability whether breathing within the area sickens that creature.
5th (Instantaneous): You attempt to entangle all targets within the area. You might fill the area with chains, viscous glue, or quick-hardening cement. Each target must succeed at a Reflex save or be entangled and anchored in place for a number of rounds equal to the level of the spell slot expended. Creatures that enter the area after you use this ability are not entangled.
6th (Environmental): You reduce the hardness of objects within the area by 50% (Fortitude negates), or increase their hardness by 10 (to a maximum of double their normal hardness).
