How many parallel processes can I run at once?

[Aevin]

I have a weapon that bestows a certain skill when equipped. The event that checks for the equipped item is a parallel process, and it's working perfectly.

But what if I want multiple weapons that teach different skills? The help file says running multiple parallel processes can lead to problems, but is really vague about how many I can run. Can someone elaborate, please?

You can run as many parallel processes as you want if they don't interfere with each other or screw up the scripting.

...but if you have too many running at once, they can cause lag. Adding some Wait 1 Frame commands in them will help a bit-- or at least it appears to on my computer.

You can theoretical have 1998 parallel processes running at once. (999 common events and 999 events on the map)
Note that a parallel process run each frame and the more you have the longer time it takes to the frame.
On the other hand you can a single parallel process using more time each frame than say 3 other parallel processes.
You can't really know when you have too much running other than testing. There are no golden rule or anything.
Putting a 1 wait frame at the end of a parallel process seems to cut its cpu usage in half or thirds (assuming you have no other waits)

But it sounds like the type of thing you are doing could just have most of it in a single parallel process, so you wouldn't need many parallel processes anyways.

In my game, every monster in a map is a parallel process, because it is calculating the distance between it and the player. I don't get any lag doing this with an average computer (and that's over 20 parallel processes sometimes). But I do put waits in the parallel process, and that's important to do.
