Ruin
Golem
I just triggered a Goblin Invasion both naturally and with a Battle Standard when in Heartless mode. It's working.I've played some more until now, and I triggered a Blood Moon event, so I suppose we're good. No Eye of Ctulhu or Goblin Invasion so far, though. Not sure if it's working completely, or if it's just the game registering my health (about 155) before I had the Heartless node.
