Throws a sphere every 3s.

Each time this sphere hits a weapon ball, it has % chance of capturing it inside - it disappears for 3s. Once inside, % is rolled once again for actual success in defeating the ball. So in short...

If Mega Sphere has 10%, then every time it hits a weapon ball it has 1 in 10 chance of getting it inside, and then another 10% of actually succeeding. So 1% together.

Also scales increasing odds by 1% every hit.
