I`ve seen a lord + a small group of friends from a Gray Knights army taking on posseseds, rubrics and a lord before dying from an excess of 50 shots

(they used a small cardboard box for the dice) the whole room missed him (well, except the chaos players on the other side of the table).
PS An excess of 200 rolls were made by the GK player for the lord and such, less than 20 of `em were under 3
That guy
