A Hot Time is a 3 part quest by Giovanni. The first part is pretty simple by crafting honey bandages and 1 stardust lantern.
Make 2 reinforced gloves at the Tailor, 3 lava hammers at the Gadget Shoppe, and send Giovanni to Mount Cinder.
Obtain at least 1 obsidian shard from exploring Mount Cinder. Craft 1 obsidian blade at the Woodshop and 1 obsidian-button pouch at the Tailor.
