[RPG] Do magic items lose their magical durability in an Antimagic Field

antimagic-fielddamage-resistancednd-5emagic-itemsspells

The DMG says this about magic item durability:

Most magic items are objects of extraordinary craftsmanship. Thanks to a combination of careful crafting and magical reinforcement, a magic item is at least as durable as a nonmagical item of its kind. Most magic items, other than potions and scrolls, have resistance to all damage. Artifacts are practically indestructible, requiring extraordinary measures to destroy.

Antimagic field's interaction with magic items is defined as such:

The properties and powers of magic items are suppressed in the sphere. For example, a +1 long sword in the sphere functions as a nonmagical long sword.

So would an antimagic field suppress the damage resistance of magic items, allowing them to be destroyed more easily? If this is true, then destroying artifacts would be trivial with a high-level caster.

Best Answer

Regular Magic Items? Yes.

You've already provided the only relevant quote from Antimagic Field:

Magic Items. The properties and powers of magic items are suppressed in the sphere. For example, a +1 long sword in the sphere functions as a nonmagical long sword.

If you want to see high-level characters flee like scared children, break out an antimagic field alongside black puddings or rust monsters.

Artifacts? No.

You've skipped an earlier part of the spell description (emphasis added):

Spells and other magical effects, except those created by an artifact or a deity, are suppressed in the sphere and can't protrude into it.

Artifacts are created with techniques that are simply better than normal spells.
