Stormsurge

Upon reaching 100 energy, Raszageth shields herself with a crackling barrier of electricity that absorbs 9000 damage. Raszageth pulses while the shield holds, inflicting 1.25 Nature damage to all players every 1 sec sec, growing in intensity by 200% with each pulse.

After 25 sec the shield explodes, inflicting 20 Nature damage to all players every 1.5 sec sec for 90 sec.
