Human, start 8 STR 8 DEX 16 CON 12 INT 18 WIS 8 CHA. All ability increases in WIS.
1-20: Cleric (Domains Healing, Trickery), Silent Spell, Toughness, Zen Archery, Extend Spell, Spell Penetration, Greater Spell Penetration, Empower Spell, Maximize Spell
21: Wizard 1, Great Wisdom I, (Wizard bonus: Scribe Scroll)
22-40: Druid 1-19, Great Wisdom II-VI, whatever you want (I suggest Dragon Shape for fun)
Wizard 1 is so arcane banners work on you. Other than that, you have all the heals. Well over 50 per rest between cleric and druid slots. Very few of the feats actually matter besides silent spell, zen archery helps for leveling. You can take Craft Wand if you want to double dip on what the character does. Ends at 34 base WIS.
HP: 716 with +12 CON.
