IRON GOLEM vs WALL OF FORCE

[Dandu]

Beat me to it. I'll also add that Wall of Force also has a duration of instantaneous; the magic used to create it is there for a split second and then gone. The wall of force itself has already been generated and isn't magical, RAW (though I wonder what non magical ongoing condition can maintain such a force....)

Perhaps it generates a stable EM barrier.

Could be a scroll

In which case the scroll's caster level is used.

I read the query as the party using this to trap the Golem by creating a wall.

I'm answering the query as closely as possible to the way the OP phrased it.

I think the OP was asking because if the wall was created or sustained by magic, there might be some doubt as to whether it could stop a golem

Blocking the golem's path was covered. What was not mentioned by other posters was using the spell to "retain an Iron Golem". Literal yes, but I'd rather have all bases covered in a discussion.

re·tain
/riˈtān/
Verb
Continue to have (something); keep possession of: "the house retains many original features".

I know. I was offering a suggested answer to your question. The dictionary quote was also unnecessary.
