Note #1: Manticore gear comes in only one variety. It is Grandmaster armour, and has Grandmaster gear bonuses, but doesn’t have Grandmaster in the name, like the others do.
Note #2: Grandmaster Wolven gear – unlike the rest – does not need the previous set of gear in order to craft it.
Note #3: There’s also the Viper School gear, but that’s special, and also another story.
