6 Divine Might
9 Still Spell
12 Spell Penetration - Improved Critical
14 Cleave
15 Extra Smiting

30 Automatic Still Spell I
32 Great Smiting I
33 Automatic Still Spell II
36 Great Smiting II - Great Smiting III
39 Great Smiting IV

Raise Charisma ever four levels
I opted not to take Autmatic Still Spell III since most of the 7th to 9th level spells I cast are Verbal only anyway(Mordenkainen's Disjuction, Power Word Stun, etc.)

Spell Selection (from memory so I may miss a couple)
1 - True Strike, Shield, Mage Armor, Protection from Evil, Magic Missile
2 - Bull's Strength, Eagle's Splendor, Endurance, Flame Weapon
3 - Keen Edge, Gust of Wind (For the cloud type spells), Lightning Bolt, Haste
4 - Elemental Shield, Evard's Black Tentacles, Improved Invisibility, Ice Storm
5 - Bigby's Interposing Hand, Metil's Acid Sheath, Dominate Person (For those with weak Will Saving Throws)
6 - Bigby's Forcefull Hand, Isaac's Greater Missile Storm, Greater Stone Skin
7 - Power Word Stun, Prismatic Spray
8 - Greater Sanctuary, Premonition, Mass Charm (Also a Verbal only spell used when fighting a group of Fighter types with weak Will Saves)
9 - Mordenkainen's Disjunction

Feel free to give me any ideas on how I can improve him. All ideas welcome.
