Aspect of the Behemoth

You are able to channel the primal endurance and strength of some of the largest and most powerful beasts on the Material Plane.  Until the spell ends, the target of the spell gains the following benefits:

• The target gains advantage on Strength checks and saving throws.
• Upon succeeding a Constitution saving throw on an effect that deals damage, the target takes no damage.  On a failed saving throw, you take half damage.
• The target's melee weapon gains the Siege property.
• It's size increases by one size and the reach of their melee attacks increases by 5 ft.
