If jumping at a place that is a long way down, you will probably die or get hurt. If there is a guard nearby, try to jump down on him so that he takes the damage. Note: You can go into the silent drop while hitting him, so nobody will hear him scream. If there are no guards nearby, go into the silent drop, and when you touch the ground, quickly hold Jump. If done correctly, you will only get about 25% of the damage that you would normally receive by such a drop. You can land quieter by crouching immediately before you hit the ground.
