Seed

Seed (Ammo) was introduced in the 1.0.5 patch.

''Confirmation needs to be made if this is really called Seed (Ammo for Blowpipe) or just Seed. If it is in fact Seed please make the appropriate page move. There will be a conflict with the page name Seed that lists all the seeds in the game, so this might be an issue.''

It is called Seed and can be gathered from Grass. Is used for a Blowpipe which can be acquired from above ground chests in new worlds generated after 1.0.5.
