Phantasy Star Cave Message Board

One time when I was playing the game when I was younger (this was about 9 years ago), I remember an item having the power of Corrosion and one having the power of Shadow (which I always thought was called Shadow Bind).

I don’t explicitly remember using them, but I do remember item descriptions mentioning it. I also forgot if they were weapons or what.

I likely just misread them, but does anyone else remember anything like this? XD

With a quick search it seems like no item is able to invoke corrosion or shadow.
For your purgatory playtrough, you might need this: http://www.wrftpb.com/psiv

in the vanilla game, there is no items that invoke either of those abilities.

in the purgatory mode hack, I believe there may be items that do.
