How can I improve my farm with Weaver?

I just started playing Weaver, and after a few games, I'm really struggling to get my farm to a point where I'm relevant as a threat.

I'm having two issues: first, Weaver's attack animation is proving difficult to last hit with (especially since the cast point is so long that I inadvertently cancel it a lot), but I'll figure that out in the long run.

The bigger issue is just killing stuff fast enough on the way to Radiance (is rushing Radiance even the optimal build?) With one or two Wraith Bands and some Treads, I'm struggling to farm efficiently. I use Shukuchi, but it doesn't do a lot of damage to the wave... what's the fastest and most efficient way to farm with him?

If it makes any difference, I'm averaging about 350 GPM in High-Skill games (I consider myself a very mediocre player, but whatever). This puts me at about a 30-minute Radiance, which is way too slow to be relevant, in my opinion.

Follow up question: what do people like to go on Weaver after Radiance?

EDIT: My issue isn't death; in three games I've died a total of once before getting Radiance. It's just that I'm getting Radiance way too late to be relevant.
