Just beat Chaos Lord in first try.
He creates a purple dragon with 21/xx states. (bug? weird. It is 10/5 on data) Then I PU it 3 times FTW!
The key to defeat him will be stop his
Discord (a purple growing blade) by Dimensional Shield early. Because if it is not stopped early, lots
and
will be lost and that means no multiple times PU. Unless it is not affordable, when you saw him put a Discord on hand, it is better to hold a Dimensional Shield on time as fast as possible.
There were lots dragons on the field waiting to eat me alive. I am so lucky back in one piece.
