See, that's why internationalization should consider defining some translation rules. There is not only "haste" but also "cast speed" right now....
btw: Let me translate it for you:
1 Chocolate = 10 Cacoas
1 Chocolate Cream = 100 Cacoas
1 Chocolate Cake = 1000 Cacoas
Blue Spinel: 8000 Cacoas
Blessing Powder: 12000 Cacoas
Lucky Powder: 12000 Cacoas
Infinium: 12000 Cacoas
Master Battle Manual Order: 12000 Cacoas
Valentine RO1 Costume Box: 10000 Cacoas
When the Master-Level-Letters event was around, one M-A-S-T-E-R-L-E-V-E-L word (= 11 letters) gave you a coin and 10 coins a box with Infinium. Therefore, the drop rate for the new Cacoas should be about 100 pieces for every letter from the mentioned event to have a similar outcome.... except that you would still not get any potions or battle manuals.
In regard of the current Kafra costs:
Blue Spinel: 75 KafraCash
Blessing Powder: 120 KafraCash
Lucky Powder: 120 KafraCash
Infinium: 120 KafraCash
Master Battle Manual Order: 200 KafraCash
Valentine RO1 Costume Box: ???
The cost for 1 Box containing an average of 100 Cacoas = 10 Chocolates = 1 Chocolate Cream is worth 1 KafraCash.
Good luck to anyone else like me who has a job and rl responsibilities.
