From what I can see, angelic potions used to cost a lot less in SP -- their overall price is shown as 39mil, but the cheapest right now are about 65mil. I'm curious as to what's made the price go up lately? Did the overall csc to sp conversion rate go up?

Look at the price of CSC.

Yes, the sp price of csc went up. Its now 47.8m for 500csc.

the angelic potion costs 750 CSC. the sP-to-CSC exchange rate is currently around 9mil sP per 100 CSC. 9 x 7.5 = 67.5, so the angelic potion is indeed worth approximately 65mil sP at this time.

ah. thank you all! im lowkey kicking myself in the shins for not buying it earlier. thank you! i like knowing the reasoning behind things
