Huntress
AmazonThis is a build for speed leveling through the campaign with spears. It works best on Deadeye and Amazon, though you can play it on mercenary as well and probably also monk.
The main interaction this build utilizes is 
Twister combined with 
Ice-Tipped Arrows and 
Barrage. Ice-tipped arrows empowers your next 4 uses of twister, converting 100% of its physical damage to cold damage and making it drop exploding ice chunks around every mob that a twister hits. Since twister can hit the same mob once every 0.66 seconds, it can drop ice chunks multiple times from the same cast on bosses. When combined with barrage, every repeat of twister will also be empowered by ice-tipped arrows. This method has much better clear speed than using twister with 
Whirling Slash, since you don't need to use whirling slash at all while clearing, and since ice chunks have much better AoE than twisters on their own.
Using this setup, I was able to complete a fresh start SSF 100% campaign speedrun (all passive skills and bonuses + 1 ascendancy trial) in 5hrs and 11mins (see video). It could definitely be done even faster by a better player.
