An outcast Shaman's Apprentice.
He was supposed to learn piety to the Earth Mother, and the Tree Man, and the Ancestors; but instead he pledged his loyalty to the Trickster Who Takes Many Forms.
This caused him to be cursed by his tribe, resulting in his youthful luck being transformed to Jinxed, and his youthful dextrousness becoming a Heavy-Handedness, among other curses.
He could no longer pick pockets or locks, nor could he sneak very well because of his cursed clumsyness. A fit punishment indeed.
But the Trickster smiled upon him and turned his curses into blessings.
His Jinx extends to others, and his Heavy Hands send others to the ground.
The medical skill that was taken from him - causing his potions to fizzle, was twisted into a knack for explosives.
His clumsyness that denied him his former skill of stealth was transformed into a strange "always falling but never hitting the ground" sort of stagger-twitch, which made him very hard to hit.
So now he avenges himself upon all he encounters: dodging, weaving, jinxing, knocking over, and exploding.
U Mad?
