What type of bug are you reporting? Mechanics
What is the bug?
In the PS dex, Hydro Steam doesn't mention anywhere (even in the expanded description) that it thaws the target. However, as coded on PS, it does thaw the target. Assuming the behavior on PS is correct, the dex description should be updated.
Are you able to replicate it? If so, how?
