Is it possible to have +x skills to a class AND a +x skills to a tree of a class?
For rares, according to Arreat Summit, "only one Prefix or Suffix will be picked per Prefix or Suffix group." When you check the general Magic Prefixes for +skills page though, "+ All Skill Levels" is listed as one group and "+ Skill Tab Levels" is listed as another group, where the former is a +skill to a class and the latter a +skill to a tree of a class. Are these considered separate groups, which would then allow a rare item to have +2 to a class and +2 to a tree?
Thanks for all the help so far. I've been asking a lot of questions and the timely answers have been really helpful in building new characters.
