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

The colossus deals double damage to objects and structures.

Any enemy outside the colossus that starts its turn within 30 feet of it must succeed on a DC12 Wisdom saving throw or be frightened until the start of the enemy's next turn. If the enemy's saving throw is successful, it is immune to this colossus's Towering Terror for the next 24 hours.

The DC requirement is increased by 2 at 4th, 8th, 12th, 16th, and 20th level, to a maximum of 22.
