Struggle and Stamina Mechanics

Demo on how the struggling works

Arm binding (Rope) Applies 10 point of Binding Points
Every successful struggle will subtract 5 Binding Points, at the cost of 10 Stamina Points.
Every failed struggle will not subtract any points, however 5 Stamina Points will be void.
When the next struggle frees you, 10 Stamina Points will be used but 5 will be refunded (Or better yet just use 5 Stamina Points)
