How good is Advantage in D&D?
Can we equate rolling with advantage in Dungeons and Dragons to a flat modifier? Let's ask this kenku we pulled off the street. Oh no, they're going on a long-winded tangent on probability... (Note for commenters: I am aware that rolling a 1 is automatically a failure for attack rolls; however in 5th edition fail-on-1 for ability checks and saving throws is an optional rule, not an official one.)

The organisers intended to break for a year between SoME3 and SoME4, so there is instead a community-run version for this year.
