Couldn't help but notice they are 15 minute recasts in the movement cancel. Does slightly 600 or so more damage than thundara.

Are they gonna share the same timer again?

Are they going to be free cost since it's a 15 minute wait?

Are they still being improved upon because 15 minutes wait for 500+ extra damage on a regular mob doe not make it seem very useful against a boss that can resist spells sometimes.
