I was progressing through the Endless Path of Od Nua last night and at one point I noticed that Hiravias is extremely sloooow and doesn't move at all in stealth mode. Browsing through his abilities I found this:

Basically looking at the unfinished description it seems like a permanent curse in Baldur's Gate games, but the devs decided not to go through with it and it only got unlocked in my game by accident. I only found this report about a similar issue here, but that's not exactly helpful:

Here's the save file:

Sadly I tend to ovewrite save files and don't have a recent one I could go back that isn't affected. I guess I could just drop Hiravias here and now, but I really like him in combat and would like to complete his quest as well. Help, please?
