Size Up. When the Blood Golem touches blood, it instantly absorbs it and grows larger. it starts out at large, but there is no limit to the size it can grow to. It grows to a higher size than before with every 4,800 fluid ounces it gains. once it reaches gargantuan size, this gain adds 5 cubic feet to its size.
Unstoppable. Due to being composed of liquid, it cannot take damage from nonmagical attacks, and magical attacks have little effect.
Drown Victim. The blood invades a victim's throat and drowns them. Melee weapon attack: +67 to hit, 5 targets large form, 20 targets huge form, infinite targets gargantuan form. hit: 999 (50d20-1) necrotic damage.
Divide And conquer. When in gargantuan form, Blood Golem can split into (4d20+5) large forms. Those forms can grow on their own and merge together.
Blood Rain. When Blood Golem reaches 100 feet in height, it can cause blood to rain from the sky, making its growth pattern unpredictable (it's up to the DM).
