I am trying to put together a list of all of the permanent magical effects that a low level character can create and leave behind, absent the permanency spell. These can be effects that hang around until activated (explosive runes), effects that endure indefinitely (arcane lock) or the creation of "real" items that don't eventually vanish (except through the normal processes of nature). I'm also excluding all the items with patches that you tear off to make things.
Parameters: Less than 6000 GP (magic item price, or spell components), spells 4th level or lower.
So far I've got:
Items
Ring of Arcane Signets
Copycat Siphon
Philter of Love
Truecolor Dye
Robe of Infinite Twine
Stubborn Nail
Tree Feather Token
Sovereign Glue
Stone of Alarm
Marvelous Pigments

What are your favorites? What have I missed?
The Hypnotism spell has a permanent effect: "Even after the spell ends, the creature retains its new attitude toward you, but only with respect to that particular request."
