Best to try to get this done during Solstice. Go into an Activity with a Solar Primary Weapon and the [b]Fired Up[/b] Solstice Modifier active; filling up the Heat Meter (by dealing Solar damage) will immediately grant you [b][u]full[/u][/b] Heavy ammo even if you have the [b]Famine[/b] and/or [b]No Starting Ammo[/b] Modifiers set. This behavior is, for whatever reason, not listed in the description of the [b]Fired Up[/b] Modifier. Pair this with a Solar Heavy and you can potentially sustain your ammo using just the Heavy by itself. (΄◉◞౪◟◉｀)

Thunderlord... I used that leveling quite a bit. Conflux is pretty easy, and ammo boxes still spawn with famine... they're all procedural spawns easy to memorize because the spaces are small. If you get one special box or heavy box that should carry to boss quickly.... My specific loadout for awhile was... Tinasha's The new arc scout Thunderlord It covers all 3 affinities... If you want to try Bakris... that's x4 surge with Light Shift for all your weapons... you get your dodge back every 2 kills to chain it with 0 cooldown. I ran, am running Prismatic... with Stylish and Ascension. Why Ascension... if you combo the 2 together it's amazing... But to be 100... to get me out dah mud. You're so much faster, my times are so much faster. Resist & Evasion. But really if you don't want to do all that... Thunderlord. To add, right this min... I'm running Ager's, same scout with redirection (because primaries suck against majors), and the Stasis Lmg from Keplar. I'd rather be on the other loadout, but I need my multiplier as high as possible. Still great, but the combo of Tinasha and Thunderlord is so so good. Every ammo box feels like Christmas. It goes from not hard, to couldn't be an easier farm.
