Spellthief (Rogue/Sorcerer)

Uniting the arcane bloodline of the sorcerer with the stealth, legerdemain and skills of a rogue, the spellthief is a figure of mystery. Unseen and unexpected attacks, either physical or magical, bolster this image. It is their signature power however, that evokes the most dread and admiration–stealing spells from their initial source, whatever it may be. By studying arcane manuscripts, or through quick and careful observation of spells being cast, the spellthief may recreate these energies, or unleash them as they see fit.

Primary Class: Rogue.

Secondary Class: Sorcerer.

Hit Dice: d8.

Bonus Skills and Ranks: The spellthief may select three sorcerer skills to add to her class skills in addition to the normal rogue class skills, one of which must be Spellcraft. The spellthief gains a number of ranks at each level equal to 6 + Int modifier.

Weapon and Armor Proficiency: The spellthief is proficient with all simple weapons, plus the hand crossbow, rapier, sap, shortbow, and short sword. She is proficient with light armor. She can cast any bloodline, filched, or stealth arcanum spells while wearing light armor without incurring the normal arcane spell failure chance. A multiclass spellthief still incurs the normal arcane spell failure chance for arcane spells received from other classes.

Spellcasting: A spellthief casts arcane spells drawn from her bloodline spells or stealthy arcanum, and spells filched from other spellcasters. She can cast any spell she knows or filches without preparing it ahead of time, with a caster level equal to her spell thief level. To cast a spell, a spellthief must have a Charisma score equal to at least 10 + the spell level. The Difficulty Class for a saving throw against a spellthief’s spell is 10 + the spell level + the spellthief’s Charisma modifier.
A spellthief can cast a limited number of spells per day. She receives 1 slot per level of spell per day that she knows, up to 6th–level, but does not receive bonus spells per day if she has a high Charisma score. The caster level of any spell cast by a spellthief is equal to her spellthief level.
A spellthief’s selection of spells is also extremely limited, more so than other spontaneous spellcasters. A spellthief can know only those spells gained from her bloodline or her stealthy arcanum class features, at the indicated levels, as shown on Table: Spellthief. A spellthief also adds any filched spell to her list of spells known until the next time she rests to regain her daily spell slots.

Cantrips: A spellthief knows a limited number of cantrips, or 0-level spells (see Stealthy Arcanum). These spells are cast like any other spellthief spell, but they do not consume any slots and may be used again.

Sneak Attack (Ex): This is exactly like the rogue ability of the same name, except that the spellthief deals 1d6 damage at 1st level, and an additional 1d6 damage at 4th level and every four levels thereafter, to a maximum of 6d6 at 20th level.

Bloodline: At 2nd level, a spellthief gains the sorcerer bloodline class ability and may choose from any of the bloodlines listed in the Core Rulebook, Advance Players Guide, Ultimate Magic, or any other Pathfinder source. She adds the skill listed in her bloodline to her class skills and gains her bloodline arcana.
At 3rd level, the spellthief adds her first bloodline spell to her list of known spells. At 7th level she adds her second bloodline spell. At 11th level she adds her third bloodline spell. At 15th level she adds her fourth bloodline spell. At 19th level she adds her fifth bloodline spell. The spellthief does not gain her bloodline powers. This ability replaces evasion, uncanny dodge, and improved uncanny dodge.

Spellfilching (Ex): Starting at 1st level, a spellthief can steal arcane spells from a variety of sources and unleash that energy at a later time. A spellthief can filch a number of spell levels per day equal to her spellthief level + her Charisma modifier. At 1st level, a spellthief can filch arcane spells of 1st–level, and the next higher level of spells every three levels thereafter to a maximum of 6th–level at 16th level.
The spellthief may attempt to filch an arcane spell from a spellcaster in the midst of casting by making an opposing Spellcraft check (DC 15 + the spell’s level) against the spellcaster’s Concentration check. If this check succeeds, the spellthief steals the spell, while the opposing spellcaster loses the spell as if it had been cast without taking effect. If this check fails, the spell takes affect as normal. A 0–level spell counts as 1/2 a spell level for this calculation.
Alternatively, a spellthief may attempt to filch an arcane spell from a spellbook, scroll, or other written manuscript by making a Spellcraft check (DC 15 + the spell’s level). Whenever a spellthief attempts to filch a spell from a spellbook or scroll, that spell immediately disappears from the page upon which it was written as if was cast directly from the scroll or spellbook, regardless of her success.
In either case, a spellthief adds the filched spell to her list of known spells until the next time she rests to regain her daily spell slots, and gains an extra spell slot of that spell level which she may use to cast the same spell, or cast a bloodline or stealthy arcanum spell of the same level or lower. This ability replaces trap finding, trap sense, and sneak attack 1d6, 7d6, and 10d6.

Stealthy Arcanum: At 1st level, a spellthief adds detect magic, mage hand, and read magic (cantrips) to her list of known spells. At 3rd level she adds vanish. At 6th level she adds invisibility. At 9th level she adds mirror image. At 12th level she adds healing thief†. At 15th level she adds mislead. At 18th level she adds ethereal jaunt. (†Ultimate Combat) This ability replaces rogue talents at 4th, 8th, 12th, 16th, and 20th level.

Talents: At 2nd level, and again every four levels thereafter, a spellthief gains a rogue talent for which she qualifies. At 13th level, the spellthief can choose advanced rogue talents whenever she could choose a rogue talent, or when she selects the extra rogue talent feat. The spellthief adds the following rogue abilities to the list of advanced talents she may select: evasion, uncanny dodge, and improved uncanny dodge. A spellthief must select uncanny dodge before selecting improved uncanny dodge. In the case of the improved evasion talent, the spellthief must have evasion to select it. A spellthief treats her level as her rogue level for the purpose of qualifying for talents with level-dependent requirements and calculating the effects of any talent or rogue ability she's chosen.

Sneakstrike (Su): At 5th level, whenever a spellthief casts a spell with q range of “touch”, she can deliver the spell as part of her sneak attack with a melee weapon. This ability otherwise functions as the magus’s spellstrike ability. This ability replaces sneak attack 4d6.

Master Spellfilching (Su): At 20th level, a spellthief who saves against a spell that targets only her (not including area spells) may attempt a caster level check (DC 10 + the spell's original caster level) as an immediate action and expend a number of spell slots the sum of whose levels equals the level of the spell in question. If the check succeeds, the spellthief can absorb the spell effect without harm and immediately recast that spell (using the original caster's level and save DC) or any other single-target spell of equal level or lower that she knows (using her own caster level and save DC), back at the caster. This ability replaces master strike.

Rogue Talents: The following rogue talents complement the spellthief multiclass archetype: black market connections†, distracting attack*, fast get away*, fast stealth, finesse rogue, guileful polygot*, major magic, minor magic, ninja trick†, offensive defense*, quick disable, rogue crawl, and snap shot*. (*Advanced Player’s Guide, †Ultimate Combat)

Advanced Talents: The following advanced rogue talents complement the spellthief archetype: confounding blades†, dispelling attack, fast tumble*, hide in plain sight†, skill mastery, thoughtful reexamining*, and unwitting ally†. (*Advanced Player’s Guide, †Ultimate Combat)
