Damage i think was 100 per level on all the chips, so the IX did 900dam. Attacks I'm not sure, I thought they all did 5/min but the V and VI do 4/min, I was sure they did 5/min so maybe the were altered.
The thing is, so few of the VII+ dropped that they can probably adjusted stats without anyone complaining, so whatever info you find out could be obsolete.
