Blowpipe

Blowpipe was introduced in the 1.0.5 patch. It can be found in the new above-ground Chests. These Chests are only placed in Worlds generated with the 1.0.5 patch.

Similar to a Bow or Gun, the Blowpipe requires ammunition to fire - but the ammunition it uses are Seeds. Seeds do not add to the damage that the Blowpipe deals. In addition, Seeds are context-sensitive items that will not begin appearing until you have a Blowpipe in your Inventory.

If you have a Blowpipe with you, there is a chance that any standard flower - and even the long grasses - you cut down will yield some Seeds. Flowers growing in grass and in Clay Pots both can yield Seeds, and you typically get 4 per "drop". Seeds dropped from long grasses typically drop singly or in pairs.
