I have a new gadgeteer character so I was looking through brawl attachments. Unsurprisingly there are not many brawl attachments. The part that sucks is the fact that you can't really use the few attachments that they give you. Out the core rulebook and Gadgets and Gear the only brawl attachments are "shock pulse emitter" and "weighted head" the problem is both of these attachments require 2 hard points and there's only one brawl weapon with 2 hard points (out of the two books), so the only options for 1 hard point attachments are "paired" and "superior". Paired is kind of niche and pretty weak since it only makes slightly easier to hit with your secondary weapon. Superior is pretty good, but cost over twice the price of any of the brawl weapons I know of.

I guess I'm just seeing if anyone else thinks that this is a problem, or if anyone knows of good 1 hard point attachments.

I think that, excluding using tinker, most brawl weapons don’t have hard points by design. Thus can be weird.

i figures weighted head might work, by really reinforcing a blunt weapon.

Isn't there an option in the crafting rules to drop the HP cost with advantages rolled? In Spec Mods. Soz, don't have the book with me.

For adding attachments, there is no Advantage since you don't roll for it. There are no rules for crafting attachments. If you are talking about crafting weapons, you can spend Advantage to add HP, and there is an option (Integral Attachment) that allows you to add +1 HP and add an Attachment of 1 or less HP.
