Spellbound Steel

Also at 1st level, you can conjure metal weapons and armor with a thought. As a bonus action, you can create a one-handed simple or martial melee weapon, summoning the metal out of thin air. As an action, you may use it to make a melee spell attack, dealing the weapon's damage + your Charisma modifier on a hit.

You can use this summoned weapon as a spellcasting focus for your sorcerer spells. The weapon disappears if you let go of it or become incapacitated.

Sword and Sorcery

At 6th level, your connection to your weapon allows you to seamlessly interweave spellcasting and combat. When you use your action to attack with your Spellbound Steel weapon, you can make two attacks.

Additionally, when you cast a spell, you can expend one sorcery point to make one Spellbound Steel attack as a bonus action.

Steel-Edged Spells

Also at 6th level, you gain further mastery over your metallic magics. When you cast a ferromancy spell that deals damage, you can choose to deal bonus damage to one target equal to your Charisma modifier.

Additionally, when you cast a non-ferromancy spell that deals damage, you can expend 1 sorcery point to change all the spell's damage to your choice of piercing or slashing and treat the spell as if it had the ferromancy tag.

Quicksteel Coating

At 14th level, your magic summons armor plating to help defend you against your foes. The first time after every long rest that you expend a sorcery point, you gain temporary hit points equal to your sorcerer level. While you have these temporary hit points, your armor class is increased by 3. If these temporary hit points are depleted, you can restore them as a bonus action by expending 3 sorcery points.

Heart of Iron

At 18th level, your command over iron and steel reaches legendary heights. You gain the following benefits:

• When you use your action to attack with your Spellbound Steel weapon, you may expend 1 sorcery point to make a third attack.
• Anytime you deal piercing or slashing damage, you may reroll any 1's or 2's on the damage dice one time. You must use the new roll.
• You gain a +2 bonus to your armor class.
