Your best bet is to just go and join a dynamis shell, any info you might find on the web is most likly in Japanese. Atleast all the dynamis diagrams I have found are jp.
Tis real simple..
Each job dose there duty, enmity works very well in dynamis!
In the end it's really up the leader if you win or loose, I mean there is no room for chatting about what to do. The best way is to have a person bark orders out and everyone just follow without question.
At first dynamis was a very evil mission with godly rewards, but know that meny older players have done it, there is a solid plan to victory formed.
And if I guy just gives you a Hour glass, without explaining any battle plan, toss it dude and find a pro to play with.
I mean your a NOOB@! if you don't plan out your major battles. Winning is fun isn't it?
