Try to break your chains and escape.

You begin to try various ways to break your bonds.

The chain behind your back is too tight for you to slip your legs through and it is far too strong to be broken by brute strength.

The chain around your neck prevents you from reaching the cell door, which is no doubt locked. You pull on this chain with just your neck, which only strains your neck muscles. Next, you use the flexibility of your subtle body to grab the chain with your hands and then legs and give it a good yank. All fail.

Desperately you kick your cot in a vain attempt to break it up into pieces which might be used as a lever. Its oaken material causes your strongest kicks to glance off it. The noise, however, arouses a guard stationed in the hallway outside your cell.

"Quiet in there or we will completely chained you from head to toe!"
