YMMV / Menzoberranzan

• Demonic Spiders:
  • Yochlol hit very hard, and require magical weapons to do any damage to them (or magic spells) at all. Unfortunately, magical weapons not identified count as non-magical, and the only way to get the spell is to start the game with it, making it unlikely you might even be able to affect one martially.
  • Driders tend to spam fireballs from a distance, and they tend to be in more open spaces that would allow them to get them off.
• Disc-One Nuke: Drizzt himself begins at level 15, at which point the players are around levels 5 or 6 (and are unlikely to be that high of a level even after beating the game), comes with two powerful scimitars, the Gwenhwyvar figurine (a rear rank, extremely accurate attack) and powerful drow chain mail. After the Temple of Dumathoin he is abducted and will not be of any use further.
• Goddamned Bats:
  • Derro Savants and Drow Priestess can be dangerous, since they spam high level spells. However, getting up close brings them to melee, which makes them infinitely weaker and more annoying than anything else.
  • Myrlochar can poison, which require spells, ointment, or the myconid fungus to be treated. And there are tons of them around Menzoberranzan. To a lesser extent, ochre jellies can also do this.
• Sophomore Slump: Considered this for SSI. While there were some graphical improvements over their previous entry, Ravenloft: Strahd's Possession, the maps were on the whole considered far too large and too empty to justify the size, there weren't as many interesting NPCs, the plot itself broke established lore in R.A. Salvatore's works (specifically the survival of Malice and Rizzen, as well as Vierna's early death), and was considered unspectacular, particularly when Ravenloft: Stone Prophet came out.
