Not all mobiles are vicious killing machines. Many will hardly notice you if you don't bother them, and of those mobiles that do attack, some are so puny as to be fairly easy to dispose of, even for novices. Many of the stronger mobiles consider it beneath their dignity to attack low-level players, but as you accumulate points they may turn their attention to you. Likewise, if you annoy them, for example by hitting them or stealing things from them, they may get angry enough to want to teach you a lesson...

MUD has a large number of mobiles, a selection of ones not too hard to find being:

• Rats
  individually not hard to kill, but there are lots of them...
• Zombies
  they block your movement, but aren't too hard to destroy.
• Skeletons
  like zombies, but faster moving and much tougher.
• Goblins
  very easy EXCEPT for number 10, who is quite awkward!
• Dwarfs
  range from very easy to very hard; gauge from their descriptions.
• Snakes
  quite difficult, mainly because they flee a lot!
• Sharks
  cold, calculating killers, be careful!
• Thief
  very hard, and he steals things too.
• Magpie
  not so dangerous, but it flees a lot (and also steals things).
• Man
  normally placid, but not the pushover he looks...
• Parrot
  puts up a fight, infuriating conversationalist.
• Raven
  minds its own business, occasionally speaks.
• Mouse
  a doddle!
• Ox
  it doesn't do much damage, but takes ages to beat.
• Dragonfly
  anyone can kill this, but some STILL use longswords "just in case"...
• Butterfly
  they don't come easier than the butterfly..!
• Ram
  moderately difficult, hates players.
• Goat
  will attack virtually anything that moves! Formidable fighter, but beatable.
• Hedgehog
  simple to kill, better just to hit it.
• Wolf
  always attacks, usually wins, a nasty piece of work.
• Wraith
  mean, fast-moving, but not inclined to attack.
• Vampire
  VERY dangerous! Casts spells, regenerates, is very strong. Avoid it!
• Dragon
  absolutely deadly! Even fleeing from it usually kills you!
