*specialeffect <effect number>{,<send_target>{,"<NPC Name>"}};
This command will display special effect with the given number, centered on the
specified NPCs coordinates, if any. For a full list of special effect numbers
known see 'doc/effect_list.txt'. Some effect numbers are known not to work in
some client releases. (Notably, rain is absent from any client executables
released after April 2005.)
<NPC name> parameter will display <effect number> on another NPC. If the NPC
specified does not exist, the command will do nothing. When specifying an NPC,
<send_target> must be specified when specifying an <NPC Name>, specifying AREA
will retain the default behavior of the command.
// this will make the NPC "John Doe#1"
// show the effect "EF_HIT1" specified by
