So I've been playing on Vaniki more in my downtime while waiting for Oakwynd to get to Velious. I was tired of not being able to find basic pots like IVU so I made a shaman. But none of the pots that work on Oakwynd work on Vaniki, every single recipe I have tried returns "You cannot make this combine because you fail to meet requirements." WTF is going on? I used the GM to get to 21 skill and have logged in and out. I've tried both a vendor sold medicine bag and a reinforced one. I've tried to combine in different zones.
Have you tried the other Alchemy recipes, the ones available on Live? At some point (I don't recall when), alchemy was revamped and a whole new set of recipes were added, many of which were stronger than the originals. To keep alchemy products from being overpowered in the early expansions, the TLPs before the expansion where alchemy changed have a different (older) set of recipes. Vaniki likely has the Live versions available.
Some recipes only work on TLP's till the get to a certain expansion PoR I think is when they change to new. Vaniki is on like VoA expansion now so it likely uses live recipes check the recipe on eq traders. For example Code: Ant's Potion (TLP Only) Charges: 1 Effect: Ant Legs WT: 0.4 Size: SMALL Class: ALL Race: ALL Stackable up to 10 EQ item ID: 14441 No longer works and you need to make Code: Philter of the Ant MAGIC ITEM Charges: 1 Effect: Ant Legs (Casting Time: 1.5) WT: 0.8 Size: SMALL Class: ALL Race: ALL Stackable up to 20 EQTC notes: Ant Legs Spell Effect: Shrinks your target, allowing them greater mobility in tight quarters. EQ item ID: 96480
