Tar

Currency Items are a type of Item in Mortal Shell. Currency Items can be consumed to acquire Tar, which can be used to upgrade the different Shell Abilities by talking to Sester Genessa.

The Tar count is shared among all Shells.

Tar can be obtained by killing enemies or consuming Currency Items. When the character dies, it will drop all the Tar it was currently holding (Currency Items won't be dropped). If the player manages to get back to where the shell died and recover the shell (before dying again), the Tar will be recovered.
