Finish Master

Battle Master
Defeat 5 or more enemies at once using a finish or combination attack
(for this trophy, find a cluster of fairly week enemies and use Majins lightning attack. I found this move the easiest, but purification would be great too because it instantly turns enemies into crystal.)

Do each of the following finishers once for 4 silver trophies.
To do a finisher, you have to do a Majin Tag team move to 3 enemies in a row while the Wind/Lighting/Fire/Purification is effecting them.
You will go in slow motion and the screen will turn green if you did it right.
The building you go into on your way to fight the boss is a perfect spot to get these trophies as there are bout 6-8 enemies clustered on every floor level.

Lightning God
Defeat over 10 enemies with a lightning finish attack
