Volcanic Armoury

Also starting at 1st level, you can create molten weapons that you use in battle. As a bonus action on your turn, you can reach into the ground and pull out a molten weapon, which appears in your hands as a simple or martial melee weapon. The molten weapon lasts until you dismiss it on your turn (no action required), it is further than 100 feet from you, or you create a new molten weapon, at which point it vanishes. As a bonus action while holding your molten weapon, you can have it become a different simple or martial melee weapon. The weapon is magical, and you can use it as a spellcasting focus for your sorcerer spells.

Additionally, when you attack a hostile creature with

your molten weapon, you gain temporary hit points equal to your Constitution modifier, which last until the start of your next turn.
