Warcaster, a Pathfinder Base Class in Two Paragraphs and One Sentence
Warcaster. A warcaster is a powerful tool of divine retribution answering to a god or some other spiritual power. Use hit dice, proficiencies, class skills, base attack, base saves, starting wealth, and starting age as a cleric. Gain 4 skill points/level. Gain spells known and spells per day as a medium, selecting spells from the cleric or inquisitor spell list.
The warcaster gains a spirit blade as a supernatural ability at 1st level. This functions as the spell spiritual weapon except as follows: the base damage is equal to the sacred weapon damage of a Medium warpriest of the same level (rather than 1d8); it threatens on a 20 and has a x2 crit multipler; the weapon has a range of 10 feet + 10 feet per class level; it uses your caster level as its base attack bonus (including multiple attacks as caster level 6th or higher); it strikes as a weapon rather than a spell (ignoring SR but subject to DR, and subject to spells and feats that augment weapons); it may take the appearance (and deal the damage type) of any weapon you wish (but once selected this cannot be changed). The spirit blade takes a full round action to summon, can be summoned an unlimited number of times per day (though never more than 1 at a time), and remains until dismissed or dispelled (as a spell). The warcaster has an arcane pool as a magus of the same level, which can only be used to augment the spirit blade. At 2nd level the warcaster gains spell combat as a magus of the same level, but attacks made when using this ability can only be made with the spirit weapon. (This functions as improved spell combat at 9th level, and greater spell combat at 15th level.) At 4th level the warcaster gains spellstrike as a magus, but attacks made when using this ability can only be made with the spirit weapon. When using spellstrike, the warcaster may choose for the spirit blade to deal no damage.
The warcaster gains no other class features. #QuickBaseClass
