One feat should be pique your intrest; Reserve feats. Basically one of the feats says; "So long you have 2lvl or higher acid spell in your memory or know it and have not spend last 2lvl or higher slot you can make acidic orb as standard action which does 1d6 damage per level memorized and know spell and it is ranged touch spell by will."<br/><br/>Basically said you can whole day shoot acidic orbs so long you have memorized or know the approariate spell and not casted it or used last slot form the levle where you know the spell. This is uselfull to both sorcerrors and wizards alike. Also in the book is a nice PrC called 'Ultimate Magus' which is like mystic theurge but it combined sorcerror/wizard spellcasting plus give some few class features (like sacrafice spell slot from wizard side to use metamagic feat in sorcerror side whitout spending full round action to do so or sacrafice spell slot sorcerror side to use spontaneously metamagic feat whit wizard spell). I am not sure of the class features because I checked them only once so I may not remember them correctly but I am sure it gived one or two class features and also I recall that you can add spell from your wizard's spell book into spells known as sorcerror side (but max level was 5lvl or lower).<br/><br/>Also it haves some new spells and magic items (usual stuff) and also haves alot disucssion to influff information regarding magic and also magicall locations which bolsters arcane spellcaster a whole year (and one of them actually gives free metamagic feat for one year).
