Shadow Dragon Wardstone

Shadow Dragon Wardstone is a wardstone. Although it's not clear where it can be used for, it allows the party the opportunity to walk past Thaxll'ssillyia in the ruined temple without trouble. This only lasts a limited amount of time though, because after standing some time in line of sight of the dragon, it will turn aggressive. This item appears in Baldur's Gate II: Shadows of Amn and Baldur's Gate II: Enhanced Edition.

It's not known where this item can be found in the temple.

In-game description
"This wardstone is a virtual area of darkness, and seems to suck the very light from space around it. The shape of the stone is hard to discern, cloaked in shadow as it is."
