There are two types of refreshing water:
Refreshing Blue Water and Refreshing Green Water
You can mint Refreshing Green Water by burning one Fish NFT at any level and paying the TDT fee of 5000 TDT (50% Locked, 50% Unlocked) and 2 $DAO. When you give Refreshing Green Water to a Fish NFT, its tweet count is reduced to 50%.
You can mint Refreshing Blue Water by burning one Fish NFT at level A and above and paying the TDT fee of 10,000 TDT (50% Locked, 50% Unlocked) and 5 $DAO. When you give Refreshing Blue Water to a Fish NFT, its tweet count is reduced to zero.
When the Refreshing Water is minted, the prepared Fish NFT is burnt.
The more the tweet count increases, the higher the probability of viral infection. Refreshing Water allows you to reset the tweet count and tweet in a fresh state.
