Ok, here's a rather simple yet odd suggestion for me to ask.
From what the description says about the Sun Flask, it SOUNDS like it's supposed to blind an enemy if it hits them, at least in my opinion. Personally, with how the flask sounds when you throw it, I think its supposed to generate the effects of a flashbang. And like coal, it doesnt do very much in the way of damage, just 1 or 2 damage.
So, lets get to the point. I think Turbine should, just for the heck of it, add a blind(or a disorient effect that's similar to ARN-01D's?) and deafness effect to the sun flask that lasts say, 6-12 seconds? The add-on would make the holiday item more festive and fun to have, for what more fun is it to blind your enemies in dungeons and in taverns? It also would make the item more valuable, especially if there is no save or the save value is high for the temporary blindness and deafness effects. Of course, monsters/players will still be unaffected by these effects if they are immune to them, so you won't be able to get past that!
But overall, it would be great if temporary blindness and deafness effects could be added onto the sun flasks that are given out during the holiday season, to make the item more festive and fun. Yes, I know there are still useless items like the festival twig and all, but...I think those items should still remain unchanged to show that not everyone gets treats all the time...
