I thought I’d share my Event Guide which I have been working on for ages - more than 6 months! @Kainboy, the master, has posted his event guide here on the forum which is very informative and a great read, but this was before all the events were updated. Now, events are expanded from 10 to 15 stages and mysterious chests as well as tougher bosses have been introduced.
I started this as a small project with the aim of helping alliance members to place in Events. As I have gotten more experience with events, so too has this guide been updated and expanded. My aim is that I will continue to update this guide as new heroes which have an impact on events are released, or when new strategies are discovered.
You can find the link to the event guide HERE
Good luck and happy eventing!
P/s if you want a video guide, @Uclapack has released some excellent videos on how to event which you can find on Youtube.
