GW2 Shadow of the Mad King ACT 4 of the Halloween event guide with detailed walkthrough. ACT started on October 31 9am PST at Lion’s Arch Grand Plaza and is mostly here for you to finish up any of the Halloween stuff and obtain Attend the Party achievement.
Attend the Party
If you didn’t get the achievement, you need to relog or zone back into Lion’s Arch!
There is an event here with Mad King says that gives you the Attend the Party achievement as well as a chest at the end that rewards you with a Witch’s Hat. You don’t have to successfully obey every command, I failed a couple and still got the achievement + chest.
If you are not sure what to do during the event, just look at right side of your screen and type the word there (i.e. /threaten)
How often does the event rerun?
On the forums, one of the Anet folks posted this..
The event will continue to run every few minutes all day long so everyone can get their hat and achievement, no worries. – Colin Johanson
However, the event appeared again at 12:50, 50 minutes after the first event.
Repeated event rewards
- Got Witch’s Hat for the first time
- 25 Trick-or-Treat bags if you don’t miss any of the commands, 10 if you miss some of the commands.
