I just picked up the English printing of Mutant, I think that it is really well done, so much so that I immediately pledged on the Genlab Kickstarter running at the moment.
I have a couple of questions regarding Gearheads and Jury-Rig skill:
1. Gearheads start with a random artifact - do we assume that they know how to use it, or should they roll Comprehend depending on the Ark's DEV level?
2 Jury-Rig: Do scrap armour/scrap weapons/Rot suits only work once unless the device is made durable? i.e they can only protect vs one hit, shoot once (per barrel), or only roll vs Rot once, regardless of their Gear points? The sections on armour (p88) and rot (p126) seem to imply that they work normally i.e that they lose points when Gear is damaged.
For example, I have a Jury-Rig Rot suit (Prot 3) and I spend a day in a Rot 1 sector. When I roll my 3 Gear dice to see if it absorbs the Rot, is the suit then immediately useless regardless of the number of Gear failures (1s) that I roll?
