The Slippers of the Assassin from the Deck of Many things are supposed to trigger a temporary invisibility the first time per encounter the equipped character kills an enemy, but it doesn't seem to be working.
After getting a kill, the item shows 0/1 on the charge, indicating it has been used, and I see a puff of smoke, but my character doesn't get a buff and enemies immediately move towards and target him anyway.
I'm not sure if this is caused by TBM or not.
My character has +65% int bonus, so I should get 1 round from the buff.
Edit: Just after posting this, I got the buff on a kill, so it's not perfectly consistent.
Yeah, I can't reproduce this anymore. The item "flipped on", and now it triggers properly. Even on barrels it grants the buff.
I went ahead and submitted a save file experiencing the bug to support@obsidian.net.
