What it is
The Earwight has no eyes. It hears a walk from a long way off, and any noise of yours locks it on. It clicks as it goes, quicker as it nears you.
How it attacks
It crouches, its clicks run together into a rattle, then it charges and bites. The bite shoves you hard, so mind any drop behind you. If you sidestep, it runs past and has to turn.
Dealing with it
Creep, or stand still, and it loses you. It goes to where it last heard you, sniffs about, and gives up. A loud noise somewhere else turns it aside.
CarefulDigging and blasts carry a long way underground, and bring it from far off.
