the mighty Lego Fireball

a big red ball of fire will appear then it'll turn in to a bunch of Legos and lay on the floor when touched they explode and do as much damage as a fireball plus 4d6 stabbing damage but the explosion does not destroy the area only the character that touches it no save throw for flying enemy's a 2d8 for land enemy's 11 and above and the save succeeds.
