Planar RifterSource Plane-Hopper's Handbook pg. 6Followers of the daemonic harbinger Cixyron invented a method of harvesting pieces from Abaddon, absorbing some of the energy into themselves and condensing other portions of it into bullets they could fire from their guns. While these methods originated among Cixyron’s followers, they have spread among a few other seasoned planar travelers. Not all planar rifters are evil, as the same methods that proved effective in slaying the celestial host are just as useful against other planar forces.
Infused Grit (Su): Each day when a planar rifter recovers grit, he can attune his grit pool to one of the following subtypes: air, chaotic, earth, evil, fire, good, lawful, or water. Whenever he is on a plane that has an alignment or elemental trait, he can switch his attunement to match one of that plane’s traits as a standard action. After reducing an outsider to 0 hit points or below, he can switch his attunement to match one of that outsider’s subtypes as a free action. He regains grit as normal from critical hits, but killing blows replenish his grit pool only if the target is an outsider.
This alters grit.Deeds: A planar rifter gains the following deeds.
Infused Bullet (Su): At 1st level, a planar rifter’s bullets carry the essence of a plane to which his grit pool is attuned, striking true against creatures that shrink from that plane’s nature. As long as he has at least 1 point in his grit pool, he gains the following benefits: if he infuses his bullets with an alignment, his bullet’s damage counts as that alignment for the purposes of overcoming DR; if he infuses his bullets with an element, half of his bullet’s damage changes to an energy type determined by the element infused: acid (earth), cold (water), electricity (air), or fire (fire).
This deed replaces the deadeye deed.
Planar Surge (Su): At 7th level, a planar rifter can spend 1 grit point as a swift action to change the attunement of his grit pool to any alignment or element. This new attunement remains for 1 minute, after which time the grit pool becomes unattuned.
This deed replaces the dead shot deed.
Breaching Shot (Su): At 15th level, a planar rifter can fire bullets with such precision that he tears temporary rifts between planes. As a standard action, he can spend 3 grit points to shoot at a location within his firearm’s first range increment and tear a 10-foot-radius portal to a plane of his choice. The rift leads to a random location on the plane that is between 5 and 500 miles from his intended destination, as plane shift. The rift remains open for 1 minute, during which time any number of willing creatures can pass through. It is a one-way rift, and it is insufficiently stable to reveal details about the environment on the other side.
This deed replaces the menacing shot deed.
Banishing Shot (Su): At 19th level, whenever a planar rifter confirms a critical hit against an extraplanar target, he can spend 1 grit to deal normal damage, and the target must succeed at a Will saving throw with a DC equal to 20 + the planar rifter’s Wisdom modifier. On a failed saving throw, the target is returned to its original plane as per the banishment spell.
This deed replaces the death’s shot deed.
Planar Resistance (Su): At 2nd level, when a planar rifter infuses his grit with the essence of a plane, he gains protection against that plane’s dangers. If he attunes his grit pool to chaos, good, evil, or law, he gains resistance to magical effects that deal damage based on the chosen alignment, such as holy smite, order’s wrath, a paladin’s smite evil attack, or an unholy weapon. If he attunes his grit pool to air, earth, fire, or water, he gains protection against the energy type associated with that element (see infused bullet). He reduces the amount of damage taken from attacks of the chosen type by 2 points per gunslinger level.
This replaces nimble.Planar Strike (Su): At 5th level, as long as he has at least 1 point in his grit pool, a planar rifter’s weapon attacks deal an extra 1d6 points of damage of the same damage type reduced by his planar resistance. Aligned damage harms only creatures of an opposed alignment. At 13th level, this damage increases to 2d6.
This replaces gun training.
