The way I read those descriptions in 3x terms is:
"Serpent Eye cabalists use orbs to focus powers of enchantment, beguiling, and ensnaring. "
Feats/Talents allow an Orb to improve the effectiveness of certain spell types,
"Serpent Eye Tradition, Metamagic Feat. When using an Orb as a focus, any mind affecting spell you cast is treated as if csat at two levels higher"
"The mages of the Iron Sigil, on the other hand, employ orbs to guard themselves with potent defenses when invoking spells of thunder or force."
Feat/talent allow an Orb to create a secondary protective effect when used as a focus for certain spell types.
"Iron Sigil Tradition, Metamagic feat. When using an Orb as a focus to cast a [Sonic] or [Force] evocation, you gain a Force bonus to AC equal to the level of the spell cast. This protection lasts for 1 round for every 2 caster levels"
"Servants of the Hidden Flame wield fierce powers of fire and radiance through their staves. "
Metamagic feat, When using a Stave as a focus, any [Fire] or [Light] evocation deals an additional 1D6 per every 2 caster levels.
"Golden Wyvern initiates are battle-mages who use their staves to shape and sculpt the spells they cast."
Metamagic feat, When using a Stave as a focus, the caster may apply the effects of the Sculpt Spell feat without increasing the spell level.
"Emerald Frost adepts use wands to help channel powers of cold and deadly acidic magic, "
Metamagic feat, When using the Wand as a focus for ray or Orb spells with the [Cold] or [Acid] descriptors, the spell deals an additional 1D6 per every 2 caster levels.
"...while Stormwalker theurges channel spells of lightning and force through their wands."
Metamagic feat, When using the Wand as a focus for ray or Orb spells with the [Force] or [Lightning] descriptors, the spell deals an additional 1D6 per every 2 caster levels.
The impression I get is that the new design philosphy is 'restrictions arent cool', so instead of limiting access to spells, the new specialist wizard will invest in feats/talents and implements to become better and *cooler* than the normal wizard.
For 3rd party/HR it then becomes simple to apply the same template for other traditions.. like...
"Crimson Reaver adepts use athame's to channel the powers of darkness and stealth."
Metamagic feat, when using an athame, any spell you cast darkens a radius around with a radius equal to 5' per spell level. This darkness allows you to Hide as an immediate action.
