Every moss can be of one or more of the kinds listed below (up to five kinds have been observed on a single moss). Multiple kinds appear in alphabetical order. Common moss seems to be special in that it cannot be harvested and only seems to appear alone.
The characteristics of the moss can be changed by someone drinking from the [Aqueduct Towers]?. You will get a message stating that the characteristics of the moss have changed ("You murmur a silent prayer to the gods, lean over the moss-covered cistern, and take a deep drink of the cool water. Your stat seems subtly enhanced, and the moss has somehow changed character a bit."). You can continue to drink from towers, but you can only change the characteristics of the moss once per teppy hour.
The change appears to be somewhat random, but each change does appear to be similar to the previous moss.
A checklist for identifying existing Moss Attributes. We have no idea as of yet what the maximum number of attributes are, or if any set of combinations are incompatible.
Known ways a moss can change characteristics:
| From | To | Added | Removed |
| green | smelly | semlly | green |
Moss regrows with unaltered characteristics 2-3 minutes after harvesting.

| 23-39 | 3 |
| 40-60 | 4 |
