bug with a dagger weapon removing stealth on rogue, weapon is named nightfall darkcaster’s kris. i only know its this cause i can swap weapons and it stops happening.
Is this the weapon?
If so, it’s because the effect of gaining int when a nearby player or enemy dies.
That likely isn’t a good weapon for your rogue though since it’s an INT dagger, so unsure if it’s a bug since it’s not intended for that class.
