Tea has always been an interesting item in Deepworld to say the least. In older world generation versions (V2 and older), tea could be found placed as a decoration in a few of the bunker and house models. This is very strange due to the fact that tea is an accessory, and no current accessories can be placed. What is even more bizarre is that tea is an accessory. Perhaps there will be a consumable use for tea in the future. For now, however, tea is simply a strange anomaly.
None, its the most useless item you will ever find!
