What I did was sacrifice up to 2000 loyalty points (easily done by marrying fatties and sacrificing them along with ToL monks) and then sacrificed another wife at 12:03 AM game-time (midnight), which got me the Maelstrom.
Then I got Hammer and immediately donated ten thousand gold, and then donated another ten thousand at 12:15 PM game-time (noon). The only reason I donated 10k the first time is because I didn't know how much I needed to donate in order to participate in whatever they call the "holy hour" donations.
