I've noticed that when I cast the spells above, and I have a few blades (Bladestorm and Balance Blade to be exact), they become frozen in the air rather than revolving around my character. But, when I cast another blade, they begin revolving normally. Not a big issue, but still an issue.
It happens because star spells set to give one thing, like critical star spell, resist star spell, etc, so the blades on you "no need to wait" until star spell ends When star spell gives more, especially at balance-star spells (because of the 5% of 3 school, boost...), it stucks at air, because it takes more time until star spell end. sometimes it waits "too much" time, so it stucks on air, until you "wake it" with another blade.
