Magic is dumb. I like to use magic, the power of the gods, and the armor optimizer to show that magic is dumb.
Stand in forest... wait for invader using homosexual magic... GMB... SMG the Crest Shield... SLB the Uchigatana... reck some heretic fools.
Only downsides are the limited effective time of miracles and magic (lingering dragoncrest and high magic resist to counteract this) and low physical defense so if you meet someone who came to their senses then you might have a run for your money.
My new favorite PVP build and the SL 131 allows for PVP with down to 125 or lower in the forest. Leave a comment if you like it or see something to improve. Thanks for feedback.
