I just notice something intresting, I have not test it yet, and I do not know if some have done this quiestion or not, just food for thought.

The Block plug in, there is a little section called Blocked Elements

This mean, if have two plug ins, you can have two type of blocks? One for "Physical" and other for "Magical" The thing is, the gain Block commands will generate for both types of blocks... which defeat the porpuse of the having multiples plugins for diferent attribitues. 

Maybe in the future, there could be an updated of the plugin that allow this, could be intresting to having a "Null-fire" which give you tons of block, but only for "fire damage" 

I just want to point that out, thanks for your time :)
