I've made 2 Dripple Pipes in order to create rain and stop stuff from smoldering. However, 3 out of 7 times I've used a Dripple Pipe so far it has caused no rain. However, even without causing rain, it seems to stop any smoldering happening at the moment.
1. Get to Summer in RoG. 2. Use Dripple Pipe a few times (not consecutively). 3. Sometimes it'll consume 1 use and stop smoldering happening at the moment, but bring no rain.
