Passage attacks questions

[DaveW]

Quick questions on walls with passage attacks:

1) In general, movement through any wall with passage attacks always costs a full movement, correct?

2) I understand that a Necromancer (or other poison immune creature) moving through a Poison Gas wall is immune from the attack... but do these creatures have to use a full action to pass through it (being immune)? I don't know of any exception, but it makes sense to me that there should be one.

3) One other case: level 1 creatures and the wall of thorns... does that require a full action? Are animals special cases with this wall?

Thanks!

It does not require a full action to move through a wall with the passage attack trait.

The exception being wall of thorns for creatures level 2 or higher.
