I'm probably gonna need some help on this...

When I gave the new Eihwaz Garapon a roll, I managed to get all 4 silvers within the garapon with 550rt. (Sadly, no golds which kind of infuriates me, but I was rolling for the silvers because yes.)

The one item that struck my senses was Arte Maid's new gun arm.
When I tested it out, it seems really amazing, so I decided to build a bot around it.
I also wanted to mix this am with one of my favorite supports in the game: Medi Aide.
This is what I came up with:

Spoiler:

I tried to create a build based around boost running, as well as being able to sway, considering sway was buffed and apparently it's dangerously good now.
The idea is to go near the crowds of enemies, shoot with the pierce gun, rack up plenty of damage, and be able to heal people.
This, combined with Growing Wonder, makes it very quick to charge up my wonder bit gauge.
The particle gun is there so I can farm items like ammo for my pierce gun (Or if someone else needs it.)

I'm sure people have suggestions considering, I'm not very good at tuning stuff. (I also tried to make a build on items that I have.)

>particle gun

no get handy mag to farm

Ok, made a little bit of revisions:

Spoiler:

Replaced Particle Gun mod in favor of Handy Magnum, seeing as how I already had a x3 high run alpha handy mag just sitting in my random Assault Ox I never use.
Also got a Shadow Master Am, And some neon neos BS for A great jump for boost run, as well as saccing a couple fly for High Tec Beta.
