Glorybound

You have bound your fate for eternity to Eyre's Glorious Blaze, the Blazoness, the solar of triumph and glory.
Choose one ability score. As long as the Blazoness is pleased by your actions, increase the chosen ability score by 2; otherwise, reduce it by two.
Additionally, you are considered proficient with every skill check that requires the chosen ability.

Your hand is replaced by a marble prosthetic. This prosthetic is a magical item and can serve as a spellcasting focus. After appeasing the Blazoness, you gain a +1 to all rolls involving this hand. Similarly, after offending the Blazoness, you gain a -1 to all rolls involving it; these bonuses are cumulative. Additionally, your weight increases by 12 kg (24 lb.).

If you ever accumulate -5, the hand loses its magical attributes. It is still connected, and due to its weight causes you great discomfort and possibly pain.
