I know the Steel Defender uses your initiative and goes immediately after you. What I’m not sure about is what is can actually do on its turn.
Does a Steel Defender get a full turn?
- Free Action (Item interaction)
- Bonus Action
I know it has the stat block that tells you what action it can take but it does not say anything about having or not having a bonus action and what it can do with that.
It also does not specify interactions
SD uses bonus action to activate boots of speed and now has the ability to move 80′ around the battlefield potentially using up AoO of enemies and positioning itself at a choke point Then takes the Dodge Action
Now we have a speedy Gonzales that can get up next to people and provide Cover, Help or be a damage sponge before zipping over the the other side to block a charging enemy that appeared from around that corner you never checked
Party member about to die SD pulls out HP potion out of bag (item interaction) and Dashes (action) to party member Party members turn take potion and drink it.
Basically a mobile Vending machine that can run in hand out potions and use its reaction to impose disadvantage.
