The information on elitegamerslounge is very good.
A lot of time goes into writing information like that and considering how usefull what is up there is, use it and have a few goes then come ask some more specific questions maybe.
Don't mean to have a go or anything, but repeating what is already up there seems silly.
Event 5, there's not really a whole lot of ways you can do it.
The write up is pretty dead nuts what everyone is doing because only about 3 guilds had to figure it out and some guilds just shared the info to the others that beat it.
Depending on which phase you are talking about as far as summon tanking. But, no, there really aren't any secrets to it. Phase 1 is probably the hardest phase now. The yellow balls can still eat ass. Phase 2 is a nice break. Phase 3 is about 75% the difficulty of Phase 1.
Phase 3 can be pretty variable in difficulty, depending on the order you get the gods to spawn in. If you get lucky on the last 2 or 3 and they go active early, it makes things a lot easier.
