Hello! Thank you so much for the feedback!
Nice to hear that the game reminded you of Morrowind. That was one of the primary inspirations! The striking sigil has a balance feature in it called “sigil toxicity” this basically acts as a complex cooldown for the weapon, but it is quite under tuned and its state not yet telegraphed to the player.
As for the issue in the Deep. We haven’t been able to replicate this bug. Where about did this happen? If you would be able to provide a videoclip of this happening that would help a lot!
Thanks for playing!
