Wrath of Acererak

Any quest that asks you to do heroics in Omu is a bit annoying because there is only one, The Tyrant, and it only pops about once an hour. Doing the other quests in the area only takes so much time and if you're unlucky, you can be in for quite a wait.

There is another option though - if you empower all nine shrines on the map, another large heroic encounter called "Wrath of Acererak" is triggered. For a long time, I never saw this even once, as shrines only stay empowered for about five minutes, which means that you need at least three people to work in tandem to trigger the event. While Omu was current content, I did this with my guildies out of sheer curiosity once, but that was it.

However, in the past week I did this heroic about five times and often did my part to empower the shrines too: It was Chult bonus week, and people get bored waiting for the Tyrant to pop. It was actually quite satisfying to see that strangers can work together to launch the event as well - all it takes is a little bit of co-ordination in zone chat. Plus I love the evil cackling sound that plays whenever you succeed in launching it.
