Neophyte Theurge: Theurgy +3, Wyrd +2, Rites: Level 1, Level 2, Level 3, Skills (choose one related to Psi power) +1.
What does it mean about Rites? You gain ONE rite of each of these 3 level? (and btw you see the error with "psi power" should be theurgic)
Same goest for Adept (there's a more clear part):
Adept Theurge (must first buy Neophyte Theurge): Theurgy +2, Wyrd +1, Rites: Level 4, Level 5, Additional rites: two rites (Level 1, Level 2) or one Level 3 rite.
Rites level 4 and 5? One of each?
The last part is simple, you know you add one level 1 and one level 2 rite OR a level 3 to your knowledge.
