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.
Prerequisites: Evil alignment, Willing Deformity, Medium size.
Benefit: 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.
Special: 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.
