K, a more detailed post on the things suggested. Shop:
Pepsi -> change to 50k.
Soft Ice Cream -> normally I'd agree but this potion has a severe issue (and that thanks to Void). It shares CD with drinks and drinks nowadays offer much better gains (50% HP/MP from Elympics Sports Drink but 60 sec CD, over 200MP and a decent amount of HP through the regular Elysion Drink, superior drinks from Elrianode and Varnimyr will be coming out in 2.5), so I question even 30k is worth this drink, maybe 15-25k or just skip this potion I don't know, even noobies can craft the superior drinks easily (as long as they have this information in mind).
Frappuccino -> Increased MP/sec buff is ignored here, it is not worth as little as 30k. Should be at least 50k (that was its event price mind you), 75k-100k seems more appropriate.
Halloween sweet basket -> 50k for complete recovery is nice but it feels too cheap for a permanent exchange, maybe 75k as well.
Espresso -> Its movement speed buff is ignored here, it should be priced at 75-100k like the Frappuccino maybe higher than that too because movement speed buff is kinda more demanded than MP/sec.
Halloween Treat -> This one is fine at 50k I guess, see how you priced this one exactly the same as the Halloween Basket that gives double the amount of HP/MP. Exchanges - Page 1:
I see you used the potion exchange I had, that's fine, just wanna say that the first exchange also has Beer and Vitality Potion, those potions are worthless compared to the other 2 so I feel like they are out of place, just a little nitpick. Crafts:
Blue Bull: This potion is not superior to a Battle Elixir, it has double the CD of a Complete Recovery whose price scales from 50k to 75k each now? Max 100k. As compensation for the double CD it also gives Full Awakening Beads (or DP for Add etc) but we have Enlightening Secret Potions for that. It should be priced at 100~150k ED in my opinion.
Pet Food: I feel 30k for Seed and 50~75k for Fruit is better, again minor nitpick.
Mage Neck and RoF Crafts: Think they are a little too cheap? Mage Neck also is a little more expensive than RoF if I recall correctly, a little more appropriate price increase could be done, maybe ~8-10:100 craft price. (I don't remember exactly their EC price though and can't be arsed to log cough).
Besides those, as others said, good idea to include Jewels as well but you are already working on that so yeah.
