Blast Acuity focused [Daikyu] Build.

I feel there's not really a point in speccing so much into single target damage, and in instances where you'd need so much single target damage, you're likely priming. This build is set up for more comfortable usage and gives a nice 5m aoe nuke. For acuity in general though, you're likely going to need some kind of aoe slow or stun for most comfortable usage, so I like to use this build paired with evade [Nova].

For invis frames, swap to [Spectral Serration]. This is the most fun and effective way to play the wep imo.
Can swap elementalist for aptitude in this instance if using a priming hound or duplex sentinel.
