In a recent match while playing as Ashe, I was able to gain ultimate charge in the spawn areas on both Place Lacroix, Redwood Dam, and Colosseo.
The prerequsites for this appear to be as follows:
- Have “Out With a Bang” as a selected perk
- Be on one of the above three maps
After spawning, but before the round starts, go to the area in the spawn room that is not covered by the healing field (meaning outside the yellow boundary field).
Throw your Dynamite. Shoot it, damage it, set yourself on fire, let it kill you.
If you shoot all three mini-dynamites and take the damage, you’ll have up to 7.5% ult charge (15% if you have the Bob Jr. power).
Winning Attitude does NOT add 15% charge per death to your ult with this method.
This was replicable both during the Armory and pre-round countdown.
I wasn’t able to replicate this on any of the other maps in Stadium, and I haven’t bothered to try in any other mode. As a guess, I’m thinking it’s because there are spots in these three particular spawn rooms that aren’t covered by the healing fields, but I can’t guess further than that. Even so, though, self-damage shouldn’t be generating ult charge, let alone doing so before the start of the round.
Mods, if this isn’t the proper venue for this, please feel free to nuke this thread and ask for evidence / replay codes / details privately.
