Opportunity attacks vs unseen servant

Question

Does an unseen servant provoke an enemy's opportunity attack?

Scenario: I disarm an enemy and use my bonus action to command an unseen servant to pick up the opponent's item and carry it away somewhere.

Will the opponent get an opportunity attack against the servant?

Notes: the text for an opportunity attack specifies that the triggering creature has to be "hostile". Given an unseen servant cannot attack, I'm thinking it cannot be hostile.

Maybe a DM may rule it can still trigger one. If a creature (intelligent or not) was in a fight and somehow passively noticed an invisible creature walking near it, it would probably assume hostility.

But that's up to interpretation. By RAW, is the unseen servant "safe" from opportunity attacks?

Answer 1

You must be able to see the creature to make an opportunity attack.

The rules for opportunity attacks state:

You can make an opportunity attack when a hostile creature that you can see

Unseen servant states:

This spell creates an invisible, mindless, shapeless, Medium force

It’s invisible, so you cannot make an opportunity attack against it, because opportunity attacks require that you be able to see what you’re attacking.

Opportunity attacks may only target creatures.

We may also observe that the rule specified that we may attack a creature:

You can make an opportunity attack when a hostile creature that you can see

Unseen servant is not a creature:

This spell creates an invisible, mindless, shapeless, Medium force

So even if you can see it, it isn’t a creature, so you still can’t attack it with an opportunity attack.
