you know what to expect from me, at least :]
If you must know, goblins have the strength of gorillas and the ferocity of rabid wolves. under a leader like Zarthag or Murgaz, they can also become a fiercely disciplined and lethal fighting force, though of course none of them have magic (as far as is known). They eat anything that moves and quite a few things that don't, and have below-average language skills, though they seem to understand one another well enough. lone packs generally are limited to clubs and spears, but "unified" groups often wear stolen armor and wield stolen or salvaged swords (which after all are simply long knives when it comes down to it).
Many a knight has made the mistake of underestimating these creatures in the past, and lost their lives (and much else besides) for it. All too often, too, the creatures use poisoned weapons, and even scratches can fester, requiring amputation if left untreated. fortunately, Paragonis can deal with most diseased or poisoned wounds, but it never hurts to be careful.
