[2020] I found a weird buff in the Queen's Gauntlet that's not on the wiki

You don't need a lot of wiki proficiency as there are various ways to help. As /u/Alcohol_Intolerant says, editing is less hard than it looks. But you also can find an article where the information is relevant, click on the "Leave article feedback" link and drop the information there. Other wiki editors will use it and change the wiki code if they find the information relevant!
