Hello, this is Kaidis. I was a Tester since 2nd Close Beta Test.
This is base on my experience from Atlantica Korean Version, I just wanted to share
the information with you guys. This will cover about Boss Fight.
*Please understand that, the name of area or monster or scroll will be different for Atlantica American Version.
However, as long as you follow the quest, the order is same as follow.
1) The Boss Fight takes place at seperated room/area
2) It is 1vs1 fight. However, you might have to fight 1vs2 battle in higher level.
3) Your party member can not join the regular Boss Fight. Party member can join only Boss fight at "Shadow Area"
4) Get use to using useful Magic Scrolls.
5) The battle is over as soon as either the Boss or your main character dies. Therefore,
try to set your main character at 3rd line.
