Ludrug

Ludrug is a gnoll NPC in the Dryad Falls area east of Gnoll Stronghold at Co-ordinates 3185, 720. The game identifies him as simply "Gnoll" but he identifies himself if it comes to a duel between champions.

'''"Our best champion is Ludrug. Ludrug is me." '''In an encounter with some strange but nonthreatening bugs, he claims the party is trespassing on Gnoll territory, and demands tribute. If the player insults him, he will go hostile, and the Gnolls that accompany him will go hostile a second later. If the player claims to have no money, he will challenge the strongest fighter. If the player refuses to "fight for your amusement", the three go hostile. Should the player accept, Ludrug goes wandering off, all the way across the map if necessary, towards what the game considers the strongest fighter in the group (quite probably the character with the most strength).[3]  He does not necessarily stick to this target. If another target is closer, left behind by, say, a character who prefers ranged weapons, who runs back to gain some extra distance, Ludrug may attack the closer target instead. If brought to below 10 HP[4]  with regular weapons, Ludrug will honor his agreement and let the players pass, but the player will get no XP. The 'knockout blow' must be dealt without weapons (the Fist icon).

In Baldur's Gate: Enhanced Edition the encounter is (maybe) a little different, and no less buggy. Or maybe it's the same, and what follows is simply a description of some of the bugs. Ludwig is most often a standard (16 hp, 35 exp) gnoll with non-standard loot, but sometimes is a more powerful gnoll worth 65 exp, the same as a Gnoll Elite, Slasher or Veteran, but with even more hp than they have: 30-32. Similarly, his three companions are usually standard gnolls with slightly better than average loot, but if you attack Ludrug after paying the toll or winning the duel, they sometimes continue to walk off the screen and are replaced by 3-5 completely normal gnolls.
