From the Introduction Sharkbait! is a short adventure for four 5th-level characters. The adventure takes place initially in the coastal town of Mochdrev, then moves into a system of underwater caverns adopted as a temporary base by a group of sahuagin. Dungeon Masters can adjust this adventure for more powerful PCs by giving levels of cleric and ranger to the sahuagin who oppose the PCs, or by increasing the number of sahuagin. The DM could also increase the size and number of the sharks that accompany the sahuagin and assist them in their attempt to eliminate the PCs. To be particularly vicious, the DM could use dire sharks or weresharks (Monster Compendium: Monsters of Faerûn, page 92) instead of the relatively innocuous natural forms presented below.
