Details:

I completed the quest that allows me to kill the boss and get this item, but I didn't know that I have to loot the boss and get the item that leads to the next quest of the alchemy quest chain, as I did some quick research I found that I'm not able to obtain the item now that I completed the quest.

If you have completed the Vault of the Wardens: Demon's Bile quest prior to the quest started by this item, but did not get this one, hit up CS as there is a bug currently preventing you from obtaining it.

It's a 100% drop and it's intended to auto-push to you upon killing Grimoira. Because you can only kill her one time within normal game progression - when you are on the Demon's Bile quest. If you kill her and don't loot the tubes - you can't get the chance to loot the tubes again, because you're no longer on the Demon's Bile quest. Open a ticket if you didn't get them.

I feel stupid... I got the bile, got credit for killing the boss, but died during the fight. Then, I never ran back in to loot the boss to get the quest. Can I do it all over again (drink the invisibility potion to open the door, kill boss) and loot the Bendy Glass Tubes? Or am I screwed?

Make a ticket and game masters will send you this item to start the quest as you cannot do the quest again to summon that special boss
