And it’s Zephyr! Specifically, Funnel Clouds seem to resolve before attenuation is applied. I’ve been successfully oneshotting acolytes with my heavy slam Melee Duplicate Magistar across both rounds.
I haven’t tested if this a property of the blast interaction with tornadoes, or if non-blast heavy slams (which are rare) also nuke enemies before attenuation applies. I also haven’t tested if this is specifically a result of Melee Duplicate shenanigans with tornadoes or if, say, Doughty builds such as the Ruvox would also work.
Zephyr stays winning!
At a locked 80 shots a second, the record holder dakka king is Grakata with the Wild Frenzy augment. A gun to try for all dakka enthusiasts.
The most I’ve managed to get is ~120 shots/sec (or ~102 shots/sec without a riven) before adding in conditional buffs. (Includes Amalgam Furax Body Count)
The Twin Grakatas also manage to just barely have more fire rate than the Grakata with 81.4 shots/sec.
