Steel Defender:
In combat, the defender shares your initiative count, but it takes its turn immediately after yours. It can move and use its reaction on its own, but the only action it takes on its turn is the Dodge action, unless you take a bonus action on your turn to command it to take another action. That action can be one in its stat block or some other action. If you are incapacitated, the defender can take any action of its choice, not just Dodge.
Upgrade:
The defender can now utilize its own Action to perform attacks, interact with objects, ect.
The Artificer can upgrade their Steel Defenders attacks further by providing upgrades, weapons, infusions, ect. This can unlock new attacks and actions for the Steel Defender to take on its turns.
