Spirit Walker Grenadier Showcase, Concussive Runes is great

I put together an attempt at a build showcase video for my Spirit Walker build. The story behind this one is simple. I wanted to make a Companion Build where both you and the companion actively attacked. I couldn't figure it out and got frustrated, moved on to Redemption and Grenade spam. I learned the way of the Owl and the Stag, and now I think its a solid jumping off point for people with way more experience in POE2 builds to see. The video is a bit long, so I'll summarize here the point and some of my pain points with the build. The POB is at the top of the post if you didn't see it assuming its working.

Basically, we are using Primal Owl's empower effect to shoot extra grenades which I believe shotguns to some extent (if not then this whole build is a waste).

The damage is pretty good in general but the gear is bad and the tree is scuffed. I'm missing an ascendancy and so on.

In terms of issues, the most important one is the particle effects. My god Cluster Grenade is a pain, Flash Grenade is a literal flashbang, and you spam dodge to escape more so than use the owl.

Concussive Runes though looks like it works with Flash Grenade really well, So it turns into an actual damaging skill. There may be more to this to look at later. The video is quite long and I'm new to videos so watch at your own peril. I won't even make it an imbed as its a whole 30 minutes.
