Immortal Treant D(12),M(2),SF(10),Dls(6)

This build abuses the fact that treant form is considered an animal and thus able to be buffed with Greater Magic Fang and Nature's Avatar through the feat Natural Spell. It also abuses the +shield ac modifier on a magic shield being melded into the tree form while removing the shield allowing full wisdom/int ac gains from monk/duelist. It is designed to remain in treant form and is capable of 74 ac with *nothing* but a +8 shield (any type). You end up with a druid cl of 20 and 5 9th level spell slots for Nature's Avatar. 45 ab even with imp combat expertise @7 attacks per round with 22 bonus physical, flame weapon, and Storm Avatar.

Only variation I like is Deep Gnome if somehow experience wasn't an issue. Even crazier AC but the +2 racial wisdom disappears when shifted.
