Thats correct. The best value in any event so far was 15cp/1 with 40% discount in treasure of the sages. Even with average of 35 points from 10keys (which is low average, usually u get around 40~) you can get 7-8 medium refines, which makes them cost 12-14cp/1. Thats a great deal. Same scenario with charm packs, between 60-70cp for a box.

However next week we will have lucky board, which is always a good investment, no matter what you are after.
