All of the following are class features of the Domestic Sorcerer.
Weapon and Armor Proficiency
Sorcerers are proficient with all simple weapons. They are not proficient with any type of armor or shield.
A Domestic Sorcerer's spell casting is Charisma based. To learn or cast a spell, he must have Charisma equal to or greater than the spell's level plus ten. DCs on his spells are Charisma based. They gain bonus spells from Charisma as well. As with Bards, they only learn spells if they have the bonus spells in that level.
A Domestic Sorcerer casts spells he knows spontaneously, as a Bard or Sorcerer does. His spells are arcane by nature, and therefor subject to spell failure from armor when using spells with somatic components. The exception to this is that a Domestic Sorcerer who has earned Light Armor Proficiency from a feat or from a different class. In such a case, a Domestic Sorcerer can cast spells wearing Light Armor with no penalty. This benefit does not apply to any other armor type, or to shields, even if the Domestic Sorcerer is proficient in their use.
A Domestic Sorcerer begins the game knowing 4 Cantrips. These are drawn from the Domestic Sorcerer spell list. He can cast these Cantrips as often as he desires. They fuel his higher level spells in place of material components. As such, he cannot cast a higher level spell for which he does not know the appropriate Cantrip. Cantrips otherwise count as 0 level spells. No more than one Cantrip effect can be active at any time. The casting time of other spells does not include the casting time of the Cantrip.
Magic Sense (Su)
Domestic Sorcerers are well attuned to the energies involved in magic use, despite knowing little about the nature of magic. Whenever a magical effect is in play within 30ft of the Domestic Sorcerer, he is able to recognize its presence by a tingling sensation in his skin. He is not normally able to recognize power or type of magic, or discern location. Extremely powerful magic, such as Major or Minor Artifacts or Epic Spells, may be noticeable from farther away, and may produce a stronger tingling sensation.
At 7th Level, the range increases to 60ft, and he can more accurately discern the power of the effect
(see Detect Magic for more information on power of effects).
At 15th Level, he is also able to concentrate on any person to determine whether they have spells available. Any caster who has spells prepared, or any spontaneous caster with unused spell slots, will register as such. The power of the person is as follows: casters with four maximum spell levels register as weak casters, casters with six maximum spell levels register as moderate casters, and casters with nine maximum spell levels register as powerful casters.
Though unrefined, a Domestic Sorcerer's power is equivalent to that of a more common sorcerer. When he casts spells, their energy registers to Detect Magic and similar effects as spells of one and a half times their level, round down. Greater Arcane Sight will show unused spell slots the same way. Effects such as the Domestic Sorcerer's Magic Sense will show him as being a nine level caster rather than a six level caster.
At 4th level, and every 5 levels after that, the Domestic Sorcerer may take any Metamagic Feat as a bonus feat.
Domestic Metamagic (Su)
The Domestic Sorcerer uses Metamagic differently than other spellcasters. When using a Metamagic Feat, he applies the effect to a Cantrip as he casts it, rather than the later spell. When he consumes the Cantrip in a higher level spell, the Metamagic effect is also applied to that spell. He can apply Metamagic levels per day as indicated in the chart. Quicken Spell only applies to the Cantrip itself, but can be otherwise spontaneously applied as normal.
Domestic Sorcerers cannot multiclass normally into Sorcerers. Instead, when they first take a level of Sorcerer, they begin to progress using normal Sorcerer spells. Take as the highest level they are able to match the spells per day in. A 6th level Domestic Sorcerer then takes one level in Sorcerer. The Domestic Sorcerer levels give one 3rd level spell, and two 2nd level spells. Their Domestic Sorcerer levels would count as 4 levels of Sorcerer, since they are able to produce three 2nd level spells in a day, the same as a third level Sorcerer. Their Domestic Sorcerer spells henceforth count as Sorcerer spells of the same level, both for spells known and for spells per day.
