Moreover, different Spirit Monsters present varying levels of difficulty. Take the Four Pests, for instance; they were personally decreed by the Jade Emperor to have their heavenly tribulations strengthened. This makes their tribulations far more dangerous than those of other Spirit Monsters, and the slightest lapse in concentration will cause their souls to be scattered by the lightning.
However, not all of the Four Pests are like this. The early stages are identical: once they survive the human-form tribulation, performing good deeds will diminish the power of subsequent tribulations. Of course, this reduction does not continue indefinitely; it can only be lowered to the level of an ordinary Spirit Monster's tribulation.
Meanwhile, the tribulation intensity for other heinous Spirit Monsters is invisibly increased, regardless of what kind of Spirit Monster they happen to be.
