My personal wishes for PC spells: Kelgore’s Fire Bolt: 1d6 fire damage/level (max 5d6), partially ignore SR. PHB 2, Wiz 1 Bigby’s Tripping Hand: Hand trips subject. PHB 2, Wiz 1 Kelgore’s Grave Mist: 1d6 cold damage/level, cause fatigue, partially ignore SR. PHB 2, Wiz 2 Blinding Color Surge: Blind subject for 1 round, gain invisibility. PHB 2, Wiz 2 Vertigo: Subject creature must succeed on a DC 10 Balance check to move each round. PHB 2, Wiz 2 There are even more in PHB 2, most of them are great. I would definitively add PHB 2 before Spell Compendium first.
