Having trouble calculating some costs.
Q 39: How much does it cost to have someone else cast Permanency (Detect Magic) on you? What about Permanent Arcane Sight?
A 39Arcane Sight/Detect Magic can't be cast by someone else on you, as they're both Personal range. I think by RAW, you wouldn't be able to recieve a Permanency from someone else on it even if you cast it yourself, but for the sake of the question:
Having someone cast a 5th-level spell for you costs 50 gp*CL, plus five time the XP cost. Permanency affecting Arcane Sight needs CL 11 and 1.5k XP, so the cost is 11*50+5*1,500=8,050 gp. For Detect Magic, Permanency requires CL 9 and 500 XP, so the cost is 9*50+5*500=2,950.
