The second part of the comments on the abilites. As for the Language issue mentioned earlier, I agree that a bonus language is rather a small boon. Give it to all the heritages, where applicable, as part of hereditary memory. As for applying CHA modifiers to other things, like DEX, I agree that it could easilly become too powerful. I like the new version of Clarity. I don't see the Druids elemental form ability as a unique and new ability, but rather an outgrowth of his other shape changing powers. As such I see why the Druid can choose the size he changes into, but still think a sorcerer should have increase by levels. Simply a Level 1 (Small to Medium) and Level 2 (Large.) But, you are right, it is easier jsut to replicate an existant ability from another class.
Metamagic Feats: The sorcerer may choose a bonus feat from the “Suggested Sorcerer Metamagic Feat by Source” table, though any necessary prerequisites must be met. Metamagic feats are handled normally, taking a full round action to augment a spell-like ability with a metamagic effect.
Players Handbook: Empower Spell, Enlarge Spell, Extend Spell, Heighten Spell, Maximize Spell, Silent Spell, Widen Spell
Examples From other WotC Sources...
Book of Exalted Deeds: Consecrate Spell, Nonlethal Substitution, Purify Spell
Tome & Blood: Chain Spell, Cooperative Spell, Delay Spell, Energy Admixture, Energy Substitution, Eschew Materials, Persistent Spell, Repeat Spell, Sanctum Spell, Sculpt Spell, Split Ray, Subdual Substitution, Twin Spell, Widen Spell
No problems here, but perhaps include them as part of the Bonus Feat list?
Oracle (Su): If the sorcerer is of the Arcane Expert, Arcane Orphan, Child of Nature, or Divine Receptacle heritage they can be blessed (or cursed) with the innate ability in the arts of Divination. Each time the Sorcerer with this ability gains a new spell level, they gain a Divination spell-like ability of that level as a bonus known spell-like ability. In addition, oracles cast all Divination spell-like abilities at a +1 caster level. If the Sorcerer also uses the typical trappings of Fortune Telling as a spell focus (such as Tarot Cards, Crystal Ball, etc.), their Divination spell-like abilities are cast at +2 caster levels.
I am somewhat hesitant to give yet another known spell-like ability per new spell level, since that is a big feature of each heritage this kind of ability is a much bigger boon than some of the others. Perhaps grant the Sorcerer the ability to replicate Divination spells with the use of Knowledge(aracana) and one of the focuses you mention. Let the DC be based on the spell level. That way a sorcerer might try to read the future in the patterns of the clouds, make a check, and then get different levels of info based on the result. This should probablly be limited to once per day. Retain the +1 per caster level to Divination spell-like abilites.
Power Manipulation (Su): If the Sorcerer has 9 or more ranks in Concentration, the Sorcerer has developed their innate control of magic to a degree where they can now manipulate the magical energy that they channel to increase its effectiveness.
Power Manipulation I: The sorcerer may increase the potency of the spell-like abilities shaped, adding up to their Charisma modifier in effective caster levels for determining spell-like ability effects. The drawback to this is that the sorcerer sustains 1d4 points of physical damage and 1d4 points of subdual damage per additional effective level of increased potency.
Power Manipulation II: If the sorcerer has 17 or more ranks in Concentration and has Power Manipulation I, the sorcerer has further developed their innate control of magic to a degree where they can now master channeling harmful pre-channeled magical energy. This allows the sorcerer the ability to attempt to absorb hostile pre-channeled magical energy. When the sorcerer is
Spellshaping (Su): If the sorcerer has any metamagic feats, they may take this ability which allows them to use metamagic in the reverse of what the feat was originally intended to do, thereby lowering the spell slot needed to cast the spell. This ability may be taken multiple times, applying its benefits to a different metamagic feat each time. Example, a sorcerer who uses the Empower metamagic feat can increase all numeric effects of a spell by one-half, and thereby increasing the spell level by two. If the same sorcerer then takes the Spellshaping ability, it would allow them to reverse the effect of the Empower feat, thus lowering all numeric effects to one-half of the original value, and taking up a spell slot two levels lower. In this way a very low powered fireball for example, could be cast using a 1st level spell slot.
OK, I see what you are doing, and I think its a good idea. I feel like there is a better way to say it, but right now I am at a loss. Sorry, I hate to offer a negative comment and not follow it up with some kind of suggestion.
Spirit Guide (Su): If the sorcerer is of the Arcane Expert, Arcane Orphan, or Divine Receptacle heritage, they can be blessed (or cursed) with a supernatural ability to channel necromantic energy and tend to focus on the world of ghosts and spirits. The sorcerer gains the following spells from the necromancer school as bonus known spell-like abilities and uses them at a +1 caster level: Disrupt Undead, Halt Undead, Animate Undead, Control Undead, and Soul Bind. Additionally the sorcerer gains the spell-like ability Speak with Dead as a bonus 3rd level arcane spell-like ability and the Create Greater Undead spell-like ability as a bonus 9th level arcane spell-like ability. These are also cast at a +1 caster level.
As with the Oracle, I'm not sure about granting additional known spell-like abilities. How about keep the +1 caster level for all Necromantic spells, allow Speak with Dead as a supernatural ability usable a number of times per day equal to their CHA modifier (or just 3 times per day)?
Summoner (Su): If the sorcerer is of the Child of Magic (Celestial or Fiendish), Child of the Elements or Divine Receptacle heritage, they can attain a specialized affinity for summoning creatures from other planes. At each spell level they gain Summon Monster of the appropriate level as a bonus known spell-like ability and use all Summon Monster spell-like abilities at a +1 caster level.
You can anticipate my comment here. Instead,how about an expanded summoning list in addition ot the increased caster level?
Towering Stature (Su): If the sorcerer is of the Child of Magic (Storm Giant) heredity, the sorcerer mysteriously gains in size after each night’s sleep over the following month until, at the end of that time they have reached the maximum height for their species – becoming of an imposing and impressive stature. The sorcerer gains a bonus to all Fortitude saves equal to their Charisma modifier, the Toughness feat, and a +1 enlargement bonus to all Intimidate skill checks.
Maybe additional levels to increase by a size catagory, with spell level prereqs?
Hope these help.
