You cause a small symbol to appear in the text of a written work. The text containing the symbol must be at least 25 words long. When anyone reads the text containing the symbol, the bookworm sigil springs into being, transforming into a swarm of ravenous worms that attack at the reader. The worms use the statistics of a leech swarm and appear in an unnocupied square adjacent to the reader.
Simply seeing the enspelled text is not sufficient to trigger the spell; the subject must deliberately read it.
The hidden sigil cannot be detected by normal observation, and detect magic reveals only that the entire text is magical.
A dispel magic can remove the sigil. An erase spell destroys the entire page of text.
Bookworm sigil can be cast in combination with other spells that hide or garble text, such as secret page.
