Altairis

You cross your arms over your head and release heavenly body magic into the air above you. Sticking your hands out in front of you, you form a massive amount of condensed magic into a single point form a black sphere about 3 feet across. Resembling a black hole the rocks and other small bits of matter surrounding it slowly begin to get pulled in as the spell alters the gravity around it. You pick a target within range and hurl the sphere towards them making a ranged spell attack. On hit the target suffers 8d6 force damage and any creature within 10 feet of the sphere before it dissapears must succeed on a Constitution saving throw including the original target or have it's movement reduced by half until the start of your next turn. When you cast this spell at a 2nd level spell slot or higher the damage increases by 1d6 for each spell slot used above first.
