How would your character react to the one above?

It's M&M

Skelly is a PL 10 super

Rolled 10, 13, 11, 18, 10, 6, 5, 9, 15, 3, 3, 2, 14, 13, 17, 17, 1, 18, 14, 12, 13, 7, 3, 1, 15 = 250 (25d20)

Idk how to use my initiative then.

Rolled 13, 20, 9, 10, 12, 12 + 2 = 78 (6d20 + 2)

And for the rest

Also, I'm amazed how the dice actually averaged out perfectly in this post.

Technically, a perfect average would have been 262.5.

10.5 is the 'average' result of a d20.
