1-level Conjuration
You create a Tiny hand out of shimmering, translucent force. This hand immediately seeks out and destroys bookworms and other creatures that eat paper and glue. The bookworm bane has a Strength of 6 (-2) and a Dexterity of 12 (+1), so it can open books to seek out insects living inside. When it finds an intrusive creature of no larger than Tiny size, it automatically hits, doing 1 point of damage, which is more than enough to automatically squish a bookworm, roach, mouse, etc. The hand has 4 hit points and will not attack anything larger than Tiny, cannot defend itself, and can perform no other actions.
