Currently based on the Official Forum Thread for Speedrunning:

• Clean: No exotics, only health pots / self revives
• Freestyle: Any pots, buffs, or exotics

Solo can be Clean and Freestyle, but Clean overrides Freestyle.

Duo, Trio, Quad are all considered Freestyle

Only Heroic Maelstrom behemoths are counted

-- Re-structure --

1. Level Leader-boards should only be the Heroic Behemoths (variants stay the same for counting)
2. Axe, Hammer, Sword, Pike, Chain Blades, Repeaters, Duos, Trios, and Quads

Weapon category is solo/clean only to simplify the boards. Groups are Freestyle.

Good idea ;P
