Hound

There is very little information on Hell Hounds as of yet, but here is what has been figured out. It seems if you attack them quickly enough with a spear you will be able to take on 2-3 with no problem. Don't wear log armor against the red ones as they burst into flames when they die.
 * They come in packs
 * You know they are about to attack by hearing a heavy breathing
 * They evolve the longer you survive
 * Eventually some will become combustable red hell hounds that will drop red gems

Common Drops are Monster Meat and Hound's Tooth
