Rust monster attack rules

[Lynos]

Hello

Some things are not clear to me regarding the rust monster attack:

- the antenna is making a "touch attack" against a metal object (let's say, a sword or an armor). What is the touch AC to roll against? Is it the character's touch AC?

- does the attack destroy all metal objects in two strikes, completely disregarding HP and Hardness?

- do magical weapons/armor get a saving throw or are subject to the same two-strike rule? (you're supposed to add 2 Hardness for every +1 of a magical object but it's meaningless if the rust monster only needs two strikes to destroy it).

Thanks!

1) Yes use the touch AC of the possessor/wielder.
2) Yes it will gain the broken condition, then on the second hit be destroyed. Both hits also only cause those effects if the item fails a Reflex save. Use either the possessors Reflex save or the items Reflex save which ever is greater. Generally that will be the wielders. It also assumes no one has used magic (Mending, Make Whole etc.) between hits to restore the item.
3) Yes that means, in a sense, magic items are just as vulnerable as non-magical items. But usually, at minimum, the magic item will have a better saving throw bonus.

Thank you.

Just a clarification regarding the saving throws:

So regular attended items get the wielder's saving throw bonus, but a magical attended item gets a separate bonus? (2+ half CL of object)

So for example, would a Flaming Burst sword get to roll with a +8 bonus? (2+ half of CL 12).

What would a +1 Breastplate roll?

Magic items would use the better of the items reflex save or the wielders.

IIRC correctly a +1 enchant requires caster level 3. So 2 + 3/2 is 3.
