You channel with Strafe (it automatically uses Hungering Arrow and builds Taeguk stacks) but you manually use Hungering Arrow to keep Momentum stacks and do some extra damage. It also helps to slow you down a bit when trying to stay in Oculus buff circles.
@@edubeck Hungering Arrow use every 2--3 seconds to proc momentum and focus and restraint ring(primary - secondary atack), momentum proc buff is now more easy because you have 5 seconds to start lose one stack, so in theory you can use HA every 5 seconds and will be fine, but people still use it every second, i think this is wrong, also when push try to use rocket storm rune on Strafe to slow down movement and proc more piercing..
