In other instances while Force Shroud is active and you know that you are being hit by a tech or Force attack, the issue is most likely that players and NPCs always have at least a 5% chance to hit with any ability, regardless of how high your defense is to that type of ability. So while Force Shroud is active, there is always at least a 5% chance that you could be hit by any tech or Force attack..
Wait what? What's the point of 200% resistance if there's still a 5% chance the ability will go through? That's just silly imho.
