Steel Defender

Adds Steel Defender (SD) Actions and Reactions to your character sheet.

Option:

Choose whether Steel Defender's Repair action charges reset with a Long Rest like a creature, or at dawn like a magic item.

• Long Rest: Everywhere else in the rulebook, "per day" is intended to mean "after a long rest". This has been clarified by Jeremy Crawford on Twitter.
• Dawn: Because it does not explicitly say per long rest, this could be interpreted as "at dawn" much like a magic item with charges such as the Wand of Magic Missles, although the wording isn't the same. The other argument for this option is that the Steel Defender is immune to exhaustion, which means it does not need to rest. Because it does not need to rest, it cannot effectively take a long rest and cannot reset its abilities using a long rest.

Features:

• SD Force Empowered Rend added as a custom attack spell as a Bonus Action in the attack list.
• SD Repair added as a custom spell as a Bonus Action in the attack list.
• SD Deflect Attack added as an action that shows as a reaction in the attack list. Damage does nothing until Artificer level 15, when Battle Smith gets "Improved Defender",  when it adds 1d4 + INT force damage to the attacker.
• Adds a custom cantrip called Mending (Artificer Constructs), which allows you to roll 2d6 to heal SD.
