A magical explosive of powerful magnitude.

Made from bluestone, unique to Ulos. It is not found in any other planes of the planarverse. (LC1-SToF)

First seen as a blue bottled potion gifted by Tarik Nowlin.

“We’ll need this at the gate.” - Tarik Nowlin, Battle at Blacklake (RPA-ADV1) 

Tarik gives you a bottle of Bluestone Fireball to destroy the gate to the Dragul outpost outside Blacklake.

If attempted to open the bottle at Tarik's campsite, he is quick to intervene, explaining its combustible nature;

“Any exposure to air and the fireball will explode, which would be very loud and could easily kill us. Let’s try to stay quiet and alive. Save the fireball for the gate.” - Tarik Nowlin, Battle at Blacklake (RPA-ADV1)

Rose of the Starlit Door used the same material in a powder form to blast a hole in Taron's Arena;

You question the merchant further and learn that a Halfling woman with a strange ring planted a satchel near the wall and then ran off before anyone was the wiser.

You notice traces of explosive bluestone powder on her shoes, and you see the Starlit Door insignia on her ring. It seems Rose had a role to play in the cult’s plot against Sabek. - Eye of Ulos (RPA-ADV4)

Some investigative work uncovers a different composition from the potion Tarik gave you at Blacklake;

It’s likely a mixture of trungle grit and bluestone that someone used to assemble an explosive device. - Eye of Ulos (RPA-ADV4)

Sleecrath presents you with a bluestone fireball, knowing that you will need it in your quest. She casts a spell on it, allowing you to use it as multiple times. It will be necessary to have in your possession, as she tells you:

“My threads tell me there are many in Ulos whose hearts desire an object like this. Find an ally who wants your fireball, and you may pull them free from time.” - Sleecrath - Silver Threads of Fate (LC1)

You will find two individuals connected by fate to the explosive: Rose and Zalic. You may free only one from their frozen state.

You may also trade it to the Klynoks in exchange for many items belonging to the Immortal Knight.

If you are extra aggressive, the explosive may instead be used to steal items collected by the Klynoks. Being outside of Ulos, you will no longer have it in your possession, as it explosed, perhaps for the final time.

Use it with care when exploring Sleecrath's woven strands of fate.
