Here's another trinket coming in Shattered Pixel Dungeon's next update!
The mossy clump interacts with level generation, making level types that are filled with vegetation or water much more common. At max level you can expect to see these two level types about 4x as often each. This provides lots more opportunities for players to use grassy or watery terrain to their advantage, or even just more seeds and dew to harvest.
In which slot do these trinkets go? Similar to an artifact, or just a slot in your backpack?
Main backpack, or one of the other bags you pick up later?
Is the effect passive by holding them, or they have to be activated (cooldown? limited charges?)
Can they be cursed, causing some interesting side effects? And lastly, how much do they interfer with seeded runs?
The current plan is a passive effect gained by holding them, You can only get one trinket per game and they cannot be cursed, but lots of effects are not purely positive. Trinkets shouldn't mess with seeds too much, although with the clump you will obvisouly see a little variance in levelgen.
So will they generate randomly at some point in the dungeon as a prize item (So you could find it on level 25)? Or will they be obtained in some unique way?
