Colosso Protetor

Protect. The Colossus may, on its turn, choose to protect a large or smaller target that is in the same space as it, so it throws itself in front of the target trying to receive all attacks directed at it. The creature is considered to have three-quarters cover and melee attacks made against it have a disadvantage, all attacks that miss the original target will be made against the Colossus against his own AC.

Siege Monster. The colossus deals double damage to objects and structures.

Stomp. Melee Weapon Attack: +8 to hit, reach 20 ft., one target. Hit: 32 (5d10 + 5) bludgeoning damage, and the target must succeed on a DC 16 Strength saving throw or be knocked prone. 

Slam. Melee Weapon Attack: +8 to hit, reach 20ft., one target. Hit: 38 (6d10 + 5) bludgeoning damage.
