Well decreases by how much? And how many targets it can then hit? And if combined with explosion will it explode on every enemy hit, or only of first one, or only on last one? If last one what if it will hit only one, will that decrease the damage, because no explosion happen?
> I watched people play the game and they never pressed it.
There can be another explanation for that, that they did not know about the button.
I can ask about practically every modifier I seen what exactly it does. "Pi" was just random example probably because it was last one behaving weird at the time I wrote it.
> Also, "Pi" decreases damage per hit, but since it allows you to get multiple hits with a single bullet, total damage increases.
Well total damage is not shown, only "Approximate damage per bullet" and that can both decrease and increase by applying "Pi", so I do not know what "Approximate damage per bullet" exactly means.
Not knowing the stats killed my run so many times. Upgrading from level 2 modifier to level 3 changed damage from something like 300 to 30000 but then in level it was not killing enemies at all.
