Ice-Tipped Twisters Amazon Leaguestarter

This 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.

Huntress Regex:

ge.+to|um.+f|eed|ills|\+eng|skin

This is my general regex I use for huntress. It highlights added damage to attacks, +skill levels, movement and attack speed, life, strength, and stun threshold suffix (useful for parry).

NOTE ABOUT 0.5:
This build got a HUGE buff in 0.5 with the introduction of the Spirit Walker ascendancy. Primal Bounty, the first owl spirit node, empowers your projectile attacks after dodge rolling, giving +2 projectiles and ~70% increased projectile speed. The Mhacha's Gift, the node behind it, triples these buffs for +6 projectiles and >200% increased projectile speed, which also means >200% increased damage from Projectile Acceleration III. This is an absurd damage and clearspeed increase for this build.

Also, there is a new unique amulet, Eventide Petals, that automatically spawns ice crystals around enemies you crit. You can proc ice-tipped arrows when hitting ice crystals with your twisters, meaning when these crystals spawn you multiply your ice-tipped damage by a lot. Should be very strong provided the twisters can hit these ice crystals.
