Phys and Mag. Protection, from what I can tell, is a straight reduction of damage.

1 protection = 1 less point of damage taken.

Of course, this is just from my observations, and I could be terribly wrong.

Thanks Terminus for the reply.
Can any GM answer this? Thanks

its anti crit

Ok a good merc proved that its really anti crit using robust protection II which increase physical protection by 46, his physical crit resistance increased by 4.6%.

Yep it's crit reduction. I will be adding more to the game with this stat including cards at some point.

Mail classes are coming back into the fore-front ^^
