Giant Skeleton

If the skeleton is subjected to an effect that allows it to make a saving throw to take only half damage, it instead takes no damage if it succeeds on the saving throw, and only half damage if it fails.

The skeleton has advantage on saving throws against spells and other magical effects.

The skeleton is immune to effects that turn undead.

The skeleton makes three scimitar attacks.
