Table: Stealth Arcanist Spells Prepared

Weapon and Armor Proficiency

The stealth arcanist is proficient with all simple weapons, plus the hand crossbow, katar (triblade), kukri, rapier, sap, shortbow, short sword, and swordbreaker dagger. The stealth arcanist is also proficient with light armor. She can cast arcanist spells while wearing light armor without incurring the normal arcane spell failure chance. Like any other arcane spellcaster, a stealth arcanist wearing medium armor, heavy armor, or using a shield incurs a chance of arcane spell failure if the spell in question has a somatic component. A multiclass stealth arcanist still incurs the normal arcane spell failure chance for arcane spells received from other classes.

Cantrips

A stealth arcanists can prepare a number of cantrips, or 0-level spells, each day as noted on Table: Stealth Arcanist Spells Prepared. These spells are cast like any other spell, but they do not consume spell slots. As with her other spells, these spells are not expended when cast.

Spellcasting

A stealth arcanist casts arcane spells drawn from the sorcerer/wizard spell list. Only sorcerer/wizard spells of 6th level and lower are considered to be part of the stealth arcanist spell list. A stealth arcanist must prepare her spells ahead of time, but unlike a wizard, her spells are not expended when they're cast. Instead, she can cast any spell that she has prepared consuming a spell slot of the appropriate level, assuming she hasn't yet used up her spell slots per day for that level.

When the stealth arcanist gains access to a new spell level (including her 1st–level spells), she adds one spell of her choice from the following spells to her spellbook: 1st–disguise self, shadow weapon, vanish; 2nd–blur, invisibility, misdirection; 3rd–displacement, invisibility sphere; 4th–invisibility (greater), shadow conjuration, shadow step; 5th–seeming, shadow evocation; 6th–mislead, shadow walk. For example, she can add either disguise self, shadow weapon, or vanish to her spell book at 1st level. At 4th 1evel, she can add one of the 2nd-level spells to her spellbook, and so on. Also, the stealth arcanist adds the following sorcerer/wizard spells to her spell list as 6th–level spells: ethereal jaunt, expend, invisibility (mass), limited wish, polymorph (greater), protection from spells, shadow conjuration (greater), teleport (greater). This supersedes these spell’s normal spell levels.

A stealth arcanist cannot use spell completion or spell trigger magic items (without making a successful Use Magic Device check) of sorcerer/wizard spells of 7th level or higher, unless they are on her altered spell list.

A stealth arcanist otherwise learns, prepares, and casts spells as an arcanist of her level, but her base daily spell allotment is given on Table: Stealth Arcanist under “Spells per Day.” She also receives bonus spells per day if she has a high Intelligence score.

Thief's Spellbook (Ex)

The stealth arcanist incorporates elements of a personalized secret code into her arcane writings. Creatures with whom she does not share this code take a –4 penalty on skill checks involving the stealth arcanist's spellbook. The stealth arcanist's spells (not including cantrips) take one extra page each in her spellbook. At each new stealth arcanist level, she gains only one new spell of any spell level or levels that he can cast (based on her new stealth arcanist level) for his spellbook. At any time, a stealth arcanist can also add spells found in another arcanist’s or wizard’s spellbook to hers. In all other respects, a stealth arcanist's spellbook functions as a normal arcanist’s spellbook.

Arcanist Exploits

This is exactly like arcanist ability of the same name, except that the stealth arcanist gains an arcanist exploit at 1st level and again at 3rd level and every three levels thereafter. A stealth arcanist can select an exploit from those listed in the arcanist class description or from the new arcanist exploits listed below. In addition, a stealth arcanist can select any rogue talent that she qualifies for in place of an arcanist exploit. Her rogue level is equal to her stealth arcanist level for the purpose of qualifying for rogue talents.

Sneak Attack (Ex)

At 1st level, a stealth arcanist gains the rogue’s sneak attack ability, except that the extra damage is equal to 1d6 at 1s level, and increases by 1d6 every four levels thereafter, up to a maximum of 7d6 at 19th level.

Evasion (Ex)

At 2nd level, a stealth arcanist gains the rogue’s evasion ability. This ability, uncanny dodge, and improved uncanny dodge replace the arcanist exploits gained at 3rd, 9th, and 13th level.

Sneakstab (Ex)

At 3rd level, a stealth arcanist’s limited weapons focuses her ability to deal sneak attack damage with daggers and similar weapons to such a degree that she can deal more sneak attack damage with those weapons at the expense of sneak attacks with other weapons. When she makes a sneak attack with a dagger, katar (triblade), kukri (including war kukri), punching dagger, shortsword, or swordbreaker dagger, she uses d8s to roll sneak attack damage instead of d6s. For sneak attacks with all other weapons, she uses d4s instead of d6s.

Uncanny Dodge (Ex)

At 5th level, a stealth arcanist gains the rogue’s uncanny dodge ability.

Uncanny Dodge (Ex)

At 8th level, a stealth arcanist gains the rogue’s improved uncanny dodge ability.

Tricky Spells (Su)

At 8th level, a stealth arcanist can cast her spells without their somatic or verbal components, as if using the Still Spell and Silent Spell feats. Spells cast using this ability do not increase in spell level or casting time. She can use this ability 3 times per day at 8th level and one additional time per every three levels thereafter, to a maximum of 6 times per day at 17th level. The stealth arcanist decides to use this ability at the time of casting. She can only expend 1 point from her arcane reservoir on this ability at a time.

Greater Exploits

This is exactly like the like arcanist ability of the same name, except that the stealth arcanist gains this ability at 12th level. A stealth arcanist can select a greater exploit from those listed in the arcanist class description instead of a normal exploit, or from the new greater exploits listed below. In addition, a stealth arcanist can select any advanced talent that she qualifies for in place of a greater exploit. Her rogue level is equal to her stealth arcanist level for the purpose of qualifying for advanced talents.
