Fernando, reincarnated as halfling post Chelcon.

He has finally fixed the flaws in his spell preparation and broken past his limits to level beyond first circle and be a proper wizard

Wizard (Conjuration)
Opposition Schools: Illusion, Enchantment
Strength 9
Dexterity 9
Constitution 11 (9)
Intelligence 13
Wisdom 6
Charisma 7
Feats: Eschew Material, Scribe Scroll, Spell Focus (Conjuration), Childlike (halfling racial feat)
Depending on how far past Chelcon he is and how much he has leveled, he may also know, Opposition Research (Illusion) (Well mostly, he still struggles some with learning new illusion spells but the illusion spells he has learned he can prepare consistently), Combat Casting, Augment Summoning, Quick Preparation.

He favors conjuration, divination, and transmutation.
