[Spoilers] How to trigger Heroic mode for Taken Blights public event!

Hey guys,

back with another quick infotip.

As event spawns, there is one main blight which spawns smaller dome blights to its side. If you step in and out of the smaller blights, you receive a buff blight receding. This allows you to damage main blight, which would otherwise be immune. Deal enough damage to main blight to spawn a new boss "Blightmaker". Kill it to complete Heroic difficulty.

Cheers guys!
