In patch 3.9 Janus can now achieve the **No Scope** award:

> As Janus hit at least two enemy gods with your ultimate at max distance.

Janus's ult appears to travel through the entire map.  It casts portals **[for the first 500 units][1]**, but appears to do damage throughout its path.  I note that:

> Distance Scaling: 200% of your Magical Power at distance greater than 800.

...which suggests that it goes beyond 800 units (is that correct?).

I have been playing Arena, firing the ult from my fountain into the opposite minion portal (i.e. where my team's minions exit the map).  I have hit multiple enemies in this area.  This has not given me the award.

According to this **[question][2]** Arena is around 500 units long.  However, **[someone][3]** has unlocked it on Clash at what appears to be a smaller distance than my Arena efforts.

What actually counts as "max distance" for this award?
