A very long time ago, the charged attack of the Bolt Staff used to leave the symbol of Aqshy branded on whatever it hit. I thought that maybe it was removed intentionally and never questioned it.
It wasn’t until recently that I’ve noticed the impact of the bolt briefly leaves a lingering spark and glow as if the brand was still there. This makes me think that maybe its disappearance could be bug related.
Most easily observable by firing the charged bolt at the skulls hanging near the Bridge Of Shadows, in the Keep.
