  Level 3: Battle Ready
Your combat training and your experiments with magic have paid off in two ways.   Arcane Empowerment. When you attack with a magic weapon, you can use your Intelligence modifier, instead of your Strength or Dexterity modifier, for the attack and damage rolls.   Weapon Knowledge. You gain proficiency with Martial weapons. You can use a weapon with which you have proficiency as a Spellcasting Focus for your Artificer spells.   Level 3: Steel Defender
Your tinkering has borne you a companion, a Steel Defender (see the stat block below). You determine the defender’s appearance and whether it has two legs or four; your choices don’t affect the defender’s game statistics.   The defender is Friendly to you and your allies and obeys you. It vanishes if you die.   The Defender in Combat. In combat, the defender acts during your turn. It can move and take its Reaction on its own, but the only action it takes is the Dodge action unless you take a Bonus Action to command it to take an action. If you have the Incapacitated condition, the defender acts on its own and isn’t limited to the Dodge action.   Restoring or Replacing the Defender. If the defender has died within the last hour, you can take a Magic action to touch it and expend a spell slot. The defender returns to life after 1 minute with all its Hit Points restored.   Whenever you finish a Long Rest, you can create a new defender if you have Smith’s Tools in hand. If you already have a defender from this feature, the first one vanishes.     Level 5: Extra Attack
You can attack twice instead of once whenever you take the Attack action on your turn. You can forgo one of your attacks when you take the Attack action to command your Steel Defender to take the Force-Empowered Rend action.   Level 9: Arcane Jolt
When either you hit a target with an attack roll using a magic weapon or your Steel Defender hits a target, you can channel magical energy through the strike to create one of the following effects:   Destructive Energy. The target takes an extra 2d6 Force damage.   Restorative Energy. Choose one creature or object you can see within 30 feet of the target. Healing energy flows into the chosen recipient, restoring 2d6 Hit Points to it.   You can use this energy a number of times equal to your Intelligence modifier (minimum of once), but you can do so no more than once per turn. You regain all expended uses when you finish a Long Rest.   Level 15: Improved Defender
Your Arcane Jolt and Steel Defender have become more powerful, granting these benefits.   Improved Jolt. The extra damage and healing of your Arcane Jolt both increase to 4d6.   Improved Deflection. Whenever your Steel Defender uses its Deflect Attack, the attacker takes Force damage equal to 1d4 plus your Intelligence modifier.
