Well, since people are talking about it ... I got to look at a friend's copy this weekend, and I think I missed something on one of the optional rules. There's a 'sidebar' in there with a 'secondary discipline' ruleset. As I saw it, it looked like the rule gave more power points, more disciplines known, and the use of the key attribute for the primary discipline to set DC's and level limits for two secondary disciplines ... Did they take something away in that optional rule, or is it just a power-up for psions?
