Guild Wars 2

The hints coupled per item in what I see as (possible) key words:

Edit 3; Merchant, expensive, forgeries? (easy to fake?), sinister/ghostly (the copper is not part of the hint).

Edit 4-5; Stealing, being chased, heritage, everyday object, carrying a sealed cylindrical case, attempt failed for today, muddy bay waters.
Productive week, failures, reflects, trivial on it’s own, power in numbers, one of Zomorros’ favorites.

Edit 6-7; Geysers, exhausted bloody sore, deadly aliens, many attempts, dulled blade, not fun.
Two months, combat, clinking noises, shelled beasts, bloodshed, charging beast, wiping the entire species if needed.

First item isn’t a whole lot of information but the Eldritch scroll is my favorite candidate. Eldritch means spooky or similar things and it is quite costly. It’s also purchased from a merchant and scrolls are easy to fake I guess.

Second item is confusing to me, the mystic coins are definitely one of Zomorros favorites, they tie in to the everyday part, it could be reflective and they get better the more you use in most recipes. However I’m not sure what stealing has to do with it, the running through an alley and the bay. Then again it would make sense as all mystic forge recipes that create weapons use a combination of an Eldritch Scroll and Mystic Coins.

The third item seems fairly straightforward but it might not be. Geysers, deadly “aliens”, clinking noises and shelled beasts all seem to point to Karka as they were called alien creatures from the sea, they are shelled and they do make weird noises. Farming them for 2 months and being willing to wipe out the species to get what you want means it’s either a lot of something or something rare. This basically leads to either Karka Shells (which don’t combine with the Eldritch scroll in the forge), the Ancient Karka shell (which doesn’t go into the mystic forge at all as far as I know), the Sclerite Karka Shell (which also doesn’t combine with Mystic Coins or the Eldritch Scroll) or maybe one of the 2 exotic Karka-like bows (Arthropoda or Crustacea) but that’d be the first time a non-mystic forge created weapon is used in the recipe for another.

Alternatively I’m looking at this all wrong and we are looking at a recipe using items like the Ghostly Doubloon. As we also don’t know the result yet it could be the Mystic Coins + Eldritch scroll which is used for weapons is wrong.
