How to lower a PMs mind stat?

[ZEO_X]

The only thing I found that lowers mind is melee weapons, but is there a better/cheaper option? Iam trying to make a pure GH-410.

So far I have been using psupedia as a guide but it doesn’t list what every ingredient does.

From that list, it looks like traps would do the trick.
