Dragon Helmet is the second-highest tier of helmets.This item was added in the Chrono Quest update. To obtain this item, players must complete the Gather 1 Amethyst before 3 days to receive the Blue Cube, and gather enough resources to make this.
Teammates can come to use if you ask them to protect you, but this can backfire as they know you're crafting, and they might betray and kill you. You can't equip gear or weapon, and you can't place fires while crafting, so if that happens, you're pretty much dead. It's a good idea to craft this inside your or your friend's base. Also, use theIkea Manual to speed up the crafting process. That way, hostile players and aggressive mobs are not an issue.
Dragon helmet doesn't require an Amethyst Helmet to craft, and it can be used to craft the Lava Helmet.
