Level: Druid 4,
Components: V, S, M,
Casting Time: 1 standard action

Area: 10-ft.-radius/level spread
Duration: 10 minutes/level
Saving Throw: Fortitude negates; see text
Spell Resistance: Yes
In an instant you cause glistening green vines to spring up at your command.
This spell functions like vine mine (page 230), except that the vines you create are poisonous (contact, 1d6 Dex/2d6 Dex). A successful Fortitude save is required only upon the first entry into the spell's area (and again 1 minute later); creatures don't have to save each time they enter (or each round they remain within). You are immune to the poison of the vines you create, and you can select a number of other targets equal to your caster level to share this immunity.
