An individual drow might perform a minor rite when she is celebrating a personal victory, and seeks to offer Lolth her due. More than a simple prayer, these rites usually involve some form of symbolic sacrifice, such as poured wine, burnt riches, or a small amount of the petitioner’s own spilled blood. Such rites require an icon, idol, or symbol of Lolth, (like an alter, or just rp a holy symbol) before which they are performed. They include the recitation of long prayers asking Lolth to accept the offered gifts and to provide even greater challenges in the days to come.
Unlike prayers, which are often uttered in public, and major rites, which are large affairs, minor rites are personal activities. They rarely involve more than one drow, and never more than a handful.
