Chaff Grenade

[tammer]

I have Utility Belt-hero that has the classic Flash-bangs, Smoke and Sleep bombs.
She is also very Stealth oriented.

We're going up against minions in (low-)power armor that gives them radar senses. These bypass most of my hero's stealth effects (other than the stealth skill itself), so I wanted to make a "chaff" grenade (Area Cloud Concealment: Radar-sense).

Looking at the points I came up with:
1 rank of Concealment (Radar) for 2PP + 1PP/rank for Ranged and + 1PP/rank for Area: Cloud == 4PP.
Is this right? Seems cheap (vs. Flash-bangs, Smoke, etc.)

It's cheap because it's specialized. Blocking vision is more expensive because practically everyone has it and it's the only natural Accurate sense.

To make it like the other Concealment effect grenades it should also have the Attack modifier on it.
