puts <<EOS
Kills all creatures of a given race.
With no argument, lists possible targets with their head count.
With the special argument 'him' or 'her', kill only the currently selected creature.
With the special argument 'undead', kill all undead creatures/thralls.
The targets will bleed out on the next game tick, or if they are immune to that, will vanish in a puff of smoke.
2013-03-15 17:51:04 -06:00
The special final argument 'magma' will make magma rain on the targets instead.
Ex: exterminate gob
