btw Poi. I there is a mistake on your sheet. I know I am not the Dm, but for your XP purchases I think this should be cleared up because this is a rule a lot of people seem to misunderstand in the 40k rp systems. (no insult intended)

The rules specifically state that each bonus to an attribute or skill must be purchased in turn. it is a cumulative cost. You cant just buy the +15 for one price. you have to buy the first +5 upgrade for 100xp, then the second for 250, then the third +5 for another 500xp. Spending 850xp total
