I am watching runs trying to get some practice in and wondering where the blue shotgun is coming from?

Questions are. I see some people run through potions quickly, I am getting sore hands for it so I have to ask, how people do that. ( I click for each one)

Is OpenMW allowed to use as long as we keep it without any mods?

Finally, if anyone has tried it, how long did they get on this? Just want to hear other experiences.

Kinda have been curious on this. Just want to hear what you think.(what is 100% in this game)
