Acidgrinder

Acidgrinder is gone from reach: the wiki lists it as unobtainable, with a past as a quest reward, and it carried a passive. It belonged to Underground Music Venue, the same hub as Cinderstring, Axe of Rhoads, Wingkeeper, Castbound and Eardrum.

What defined it was a hunt focus of Brine Storm +15 and a disturbance of +3. The stat line was decent but plain: Luck 185, Lure Speed 83, Control -0.02 and Resilience 30, with progress speed at 0. The slightly negative Control means the reeling bar would have drifted a little, though only by a small margin.

Because you cannot get it now, its value is as a reference point. A Luck of 185 with the Brine Storm focus was clearly meant as a mid-to-high tier option for its location, and the passive flag suggests the focus did more than the raw numbers show. We do not have the full details of how Brine Storm worked, so avoid assuming more than the +15 listed.

If you want something similar today, look at the venue's other rods that you can still get, such as Wingkeeper and Castbound, rather than hunting for this one.
