Your sorcerer spells and spell-like abilities count as psychic instead of arcane. You use thought and emotion components instead of verbal and somatic components when casting your spells.

This is possibly the one bloodline arcana that most fundamentally changes the base class. The first three points below are observations and the third is the rules question, but if I'm wrong on the observations I would like to be corrected as well.

1. You are no longer an arcane caster. You don't qualify for feats that arcane casters usually do, and you don't qualify for prestige classes that require you to be able to cast arcane spells either. Heck, if a prestige class says you need to be able to cast "arcane or divine spells", you still don't qualify because you cast neither. No arcane strike, and you can qualify for the Loremaster PRC, but not the Eldritch Knight PRC.

2. You no longer use somatic components, so you no longer need to worry about arcane spell failure. Go for that adamantine full plate if that's what you want (but make sure you shore up your will saves and concentration bonuses).

3. Since you cast psychic spells, you also gain access to psychic skill unlocks.

4. This one is the big question for the thread. Is the sorcerer class itself still considered as an 'arcane spellcasting class' with this bloodline? Take for instance an alternate racial trait like this one:

Half-elves occasionally seek tutoring to help them master the magic in their blood. Half-elves with this racial trait have only one favored class and it must be an arcane spellcasting class. They can use spell trigger and spell completion items for their favored class as if 1 level higher (or as a 1st-level character if they have no levels in that class). This racial trait replaces the multitalented racial trait.

Can a half-elven psychic-bloodline sorcerer pick sorcerer as his favoured class if he has this racial trait?

For that matter, if a cross-blooded arcane/psychic sorcerer takes familiar bond for his 1st level bloodline power, does he count as having a 'arcane spellcaster level" for the purpose of the improved familiar feat? (This is more than hypothetical btw, I am seriously considering taking this precise cross-bloodline combination.)

Basically, is 'arcane spellcaster class' defined independently of the bloodline arcana?
