This is the very first battle for Rhen.Just don't fight with him immediately. Just ignore him first, go outside practise more and more until level...may be level 15(i forgot what level i reached that time). This time you no need to care about your hp and mana. just keep your only magic skill to fight him...that all.
and one more, there will be third edition of aveyond coming soon!

1) The very first thing is you must seat flo at the podium, using the podium will keep the customers happy for a long time.Then if this level have 5 tables and be sure you have to wait in the podium until the number of group is enough ( in this case, 5). Do this will help you making a big chain.

2）Some events will happen that will break your chain. for examples, the baby pours water on the floor,customers need a snack or tourists need to take a snapshot. Do this before begin the big chain.

3) Often giving the drinks before starts making a big chain.

Good Luck for playing.
