The Subtle One

The Subtle One is a demonic creature with stealth abilities. It has poor sight and hearing, but when it finally does detect you, it will turn invisible. It will become visible when within close range and then attack, retreating and becoming invisible again on a successful strike, and then repeating the process. When it takes damage it will become partially visible for a split second and slow down. A quick string of attacks can counter the Subtle One.
