The KILL command is actually a non-command that only exists to warn novice users of what they can't do.
Syntax and Messaging
In DragonRealms, combat is not just a matter of typing KILL over and over until the creature is dead. There are several other commands that can be used to attack creatures. SLICE, CHOP, FEINT, THRUST, SWEEP, JAB, and DRAW all have different effects on the creature depending on which sequence you use them in and how effective the sequence is for the particular creature you are attacking. Each attack type has its own drawbacks and advantages -- just like real life!
