As a reminder the normal rules state:
Magic items, besides potions, scrolls, have resistance to all damage, and all items are immune to poison and psychic.
Additional rules
1.) Any items carried or otherwise on a creature are considered attended items, and if ever targeted use the saving throws and AC of the creature attending to the item or of the item unattended, whichever is greater.
2.) Magic items that are +2 or rare, very rare have twice the normal hit points. Items that are +3 or legendary have four times normal hit points.
3.) For magic items, you may either take the average hit points or roll and then apply the hit point multiplier.
4.) Magic items reduced to 0 hit points are broken and can’t be used until repaired. Broken items can be repaired for 10% of its cost and 8 hours.
5.) Area of Effect damage spells that harm creatures may also harm unattended objects as determined by the caster when casting the spell. Attended items are never harmed by an AoE unless explicitly stated by the ability.
6.) Equipment worn by unconscious characters is still considered attended, but not anything that had been held. Dead characters are not attending their equipment.
7.) Items are not immune to con saves if the effect could reasonably damage them.
8.) Unless explicitly mentioned, radiance AoEs do not damage objects.
9.) Magic items below their maximum hit points can be restored using mending, similar effects, or mundane repair.
10.) At the GMs discretion, some items may be especially vulnerable or immune to particular damage sources, for example a ring conferring fire immunity is likely itself immune to fire damage.[/list]
