A guide to getting the Mini Red Spark from the Mini Angry Chest sold on the gemstore.[toc]
Buy the Mini Angry Chest from gemstore (400 gems). This will grant you the Mini Angry Chest.
Talk to Evon Gnasblade inside The Vault area of Lion’s Arch. Evon paths around Lion’s Arch but he won’t talk to you unless he is inside the Vault so you will need to wait for him to get back inside the Vault (this can take a few minutes). He won’t talk to you immediately either, you gotta wait a few minutes and wait until he finishes his rumbling.
Talk to Krepet near Brill Alliance Labs in Metrica Province. This step is currently bugged on some maps and will need to wait for a hotfix to progress as Krepet won’t talk to you. If Krepet isn’t bugged, he will path around the area and tell you to head to Wayfarer Foothills and find Frostblast.
Once you talked to Krepet, go to north section of Wayfarer Foothills and look for Veteran Frostblast. He may path a bit in the area as well. Killing him will give you a buff where you have 5 minutes to run to the Maelstrom Core in Mount Maelstrom.
Run into the lava near Maelstrom Core with your Angry Chest pet out and you will get a popup message and receive your Mini Red Spark. If the waypoints are contested there are tunnels you can go through to get to to the Maelstrom Core (see map dotted path)
