Arelith

Not sure if this is a bug but I found a trap on the key chest in the dwarven ruins dungeon it's DC to disarm was 36 I had 37 skill and I constantly failed to disarm it despite passing the required DC by 1.
It was also permanent so once triggered just reset getting the same result.
This was on the second floor in the room with Rugnus.(the dwarf guy).

That's such an old area, I can only presume it has been that way for over ten years.

I'll look when I get a chance though.

Are you a rogue? Only rogues can disarm DC35+ traps. However, if you are non-rogue, you can still "recover" higher DC traps, however, that raises the DC of the trap by 10.

And most "generated" traps are permanent on Arelith.
