Alchemy one turns into one of these 4 items, can reroll again every hour
a reusable Coastal Healing Potion.
a costume item, similar to the Coin of Many Faces (except non-player models).
summons an interactable eye, which allows you to teleport to any npc hub in your current zone.
increases the proc chance of your Rank 3 BfA alchemy craftables for 10 minutes.
The BS and Engineering ones are really the only useless ones, egineerring one has NO PASSIVE that we know of.

it is a nice like 100g or something saved per use if used on weapon, but its not as good as the others...
would be nice if with it you had a higher chance for your crafted gear to warforge/titanforge too... speaking it is a titan item.
engineerring one is just shit, it does literally nothing other then "can summon some shitty minions to help you do world quests"
but really alot of these seem like things mostly to help profession alts and not your main char.
