About Storm Spirit’s Ball Lightning . According to source, if Storm Spirit is attacked by Bloodseeker’s Rupture, no matter how far he rolls, as long as he doesn’t move when he stops, he won’t lose any HP.
If Storm Spirit is attacked by Keeper of the Light’s Mana Leak, he won’t lose extra mana during rolling. But if mana is used up and he has to stop, he will be stunned.
