Deformity (Tall)( Heroes of Horror, p. 121)
Through long and painful stints on the rack, bolstered by the surgical implantation of various splints and struts, you have stretched yourself to well over 7 feet in height.
Willing Deformity (HH) , Evil alignment, Medium size,
Even though you are still technically a Medium creature, your improved height and lanky limbs grant you an additional 5 feet to your reach, thereby allowing you to strike nonadjacent squares with nonreach weapons.
You are a larger and clumsier target than you were before undergoing the height extension, giving you -1 to your AC. You also take a -2 penalty on Hide checks.
