This is a mixed bag
So I wills tart with the apology.
I apologize for all of the problems with the alchemy revamp. My only excuse is that I am new. To summarize the current bugs that are still awaiting a patch.
Alchemy Trophy is not gaining exp from any combine but the new ones.
Some of the earlier trophy tasks have trivials out of line.
Some of the OLD potions now have a shorter than intended duration.
The new throwing potions only stack to 20 instead of 100
The item exchange from old to new went badly.
All of the above has been fixed, but is awaiting a full patch. I expect the item exchange will complete on that patch, but it will be scheduled by the coders and not the design team, so I am not 100% sure on that one.
Also the potion that gave mana regen that stacked with Clairy and such. This was an oversight. While we understand that you want it back now, we want to give it more thought than just slamming something in, and instead give something more in line with the current way we are doing potions. We do plan on adding it back, and hopefully as something better, but it will be a while. While I understand it is not the news you wanted to hear, I wanted to give you the truth of it.
Now the statement is something I am not sorry for. While we did this revamp, we fixed some bugs on a few potions that were more powerful, or due to a different "quirk" cheaper than intended. The Remove poison/remove disease potions were not meant to be that powerful. 80 disease counters in 20 seconds is much more than intended.
The gate potion was not meant to be that "cheap" by selling it back with one charge for such a high price. I compromised with the gate potions and made them significantly cheaper than they were per potion, but there is no longer the exploit of selling back one charge for such a high price, so yes, the net effect is that they are more expensive. The reality of it is they were MEANT to cost 242 or so per dose, not the lower price they were per dose because of the bug.
Both of these were long standing bugs. Despite them being around for a very long time, we still want to fix bugs. Even old ones.
The other two potions that we did not replicate we saw as much more limited use. +10 to all saves for 3 minutes is just not that much, and +3 to casting level for 3 minutes...a gain... not very effective. The one thing we were told it was useful for, well not really. the curse is -100 casting levels... adding 3 more to you -30 effective casting level of make -27 is not really that much. We will consider both of these along with the stacking mana regen potions.
We really hope that people will like and buy the new stat potions from alchemists, now that they are cheaper and have an extra effect. Now that they can be sold for a reasonable price, since they do not cost an arm and a leg to make, they should go better. And it should not cost as much of an arm and a leg to level any longer, seeing the whole price structure is significantly cheaper.
SO again, I apologise for all of the errors. I hope you do really like it after you give it a chance, and all of the unfortunate bugs have been ironed out.
