Hey there, hope some are still around to read this.
My groups sometimes use chameleoline cloaks for stealth, which they work very well for, +20 stealth for what is essentially a cloaking device. However, the -30 for stationary targets wearing one seems way over the top. After all, -30 is the modifier of attacking a target you can't see at all. This would make this rare item the most potent sort of defensive item you can think of. A squad of soldiers wearing these (and IG squads sometimes get them for stealth jobs) standing still and shooting makes them almost impossible to hit for most enemies of the same caliber. Ork shootas have negative chance to hit them unless firing single shots at close range (orks like dakka), other human soldiers will are fairly certain to miss too.
Another issue is, what kinds of stationary? Simply lying motionless and hiding? In that case the -30 seems fine as you're not doing anything or moving at all. Does it count when shooting? The weapon can't be covered by the cloak when shooting, so most of it will be sticking out and fairly visible, thus it should be fairly easy to figure out where the shooter is and where to aim.
So if you agree that having -30 for enemies to hit you simply because you did not take move actions that turn is too good, how to fix it?
Idea 1: Strictly limit to penalty to when you are lying still hiding or taking total defense action.
idea 2: Nerf the cloak penalty to -10% when attacking.
Idea 3: Only allow the penalty to single shots, with decreasing penalty for semi-auto (-20), full auto (-10) and suppressive fire (0). This to show that the more you rely on luck and volume of fire the less does the cloak do.
Thoughts?
