Hi everyone!
IA brings a lot of new Items into the game which are really expensive and require alot of Ingredients. I always had my problems with all those gems and scrolls which are required for upgrades, that it became really frustrating when I had to search all the merchants in the game because I sold too many Diamonds and now I needed them for an upgrade. Besides these items always blocked inventory space which can be pretty annoying as long as you don't have a bag of holding.
So I decided to go through IA's item document and look up the amount of which gems and scrolls you need.
I hope this is helpful:

gaidin asked if the required gems for the original updates could be posted here. I hope I got all of them but if anyone knows another recipe with gems or scrolls he can pm me or post it.

Vanilla Upgrades

GEMS
Rogue Stone: 2 -->Quiver of Plenty +2(Arrows)(1); Wonderous Gloves(Bard only)(1)
Star Sapphire: 6 -->Wonderous Gloves(Bard only)(1); Dagger of the Star +5(5)
King's Tear: 1 -->Bag of Plenty +2(bullets)
Diamond: 2 -->Wonderous Gloves(Bard only)(1); Bronze Horn of Valhalla(1)
Emerald: 1 -->Wonderous Gloves(Bard only)
Beljuril 1 --> Iron Horn of Valhalla
I always had the impression that there were more gems needed for the upgrades but maybe I always was wrong...

Scrolls
Improved Haste: 1 -->Improved Cloak of Protection +2
Invisibility: 1 -->Improved Cloak of Protection +2
Protection from normal Weapons: 1 -->Aslyferund Elven Chain +5


I wrote to every gem and scroll the items which can be forged with them. The red numbers behind the items names are the quantity of the gems needed. If only one item name is listed behind one gem, you will need all gems for that one item. If I got something wrong feel free to post my mistake and I will correct it.

With this information you won't have to run to evrey merchant and look if you have sold a crucial scrolls and waste precious money for no reason.
It helped me a lot

Gorwath

Thanks, Gorwath!

The topic is pinned. I trust you will update it when IA v6 is released.

O.T. suggestion:
maybe since AI has a lot of different challenges that some might find too challenging difficult at times to deal with like the topic maybe a sub-forum could be used to contain 'notes, lists, spoilers, and or specific tactical moves for certain battles.

meh I am completely neutral as far as this goes, if just pinning is good enough, so be it.

please feel free to delete this O.T. post

That's a good suggestion, Sir-Kill!

We will certainly think of adding some subforums once IA v6 is released.

You don't need all the gems in that list for any given playthrough because some are used for upgrades for personal items of Bioware NPC's which you don't have in the party. Because gold is precious it's a good idea to check the item readme and sell those gems you won't need.

Excellent, Gorwath! I made a similar list for one of my games, but didn't think of posting it here.

Thanks for the kind words.
I will certainly update this topic when IA6 is released.

@Raven


I will add to every Gem which items you can forge so that you know if you really need to collect them

Gorwath

Good idea.

Hi 2 all.
Excellent idea with this list.
But maybe you can add the gems for those vanilla item upgrades like Iron Horn of Valhalla, Bard's Gloves, Quiver of Plenty, etc?

Ok. I'll try to get those informations and post them here in a separate reply.
But it will take some time

Gorwath

I think the itemlist is now completed. It will be updated when IAv6 will be released

Gorwath

I think you've missed needing a Diamond to upgrade the Silver Horn of Valhalla to the Bronze Horn and a Beljuril to upgrade the Bronze Horn of Valhalla to the Iron one.

Thank you Raven!
I added the Horn to the Vanilla Game Upgrades

Some more gems:

5 Jasper Gems needed for a subquest in the Expanded Mage Stronghold (PC necromancer only) - The Wine and the Sandalwood.

Also, I would like a hint to where can be found the third Bluestone Necklace in the game. I know the locations of the other two. But that item is no longer a random drop.

A though after reading the item list.

I think that maybe it is best to cancel the requirment of scrolls and gems when forging items. Instead, we can increase the gold requirment to maintain the same economic pressure on players.
To remember and storing all the scrolls and gems for later forging is too much a hassle for players. Due to the limit of BG's UI, we already have a headace in inventory management. I believe most people give them a bag of holding immediatly after starting a new game. I usually give myself a potion bag, a ammo belt, a scroll bag, a bag of holding and a gem bag. I really hate Beamdog for not mordernizing the UI aspect of BG2:EE.
It is more lore friendly and adds favor into the game by requiring scrolls and gems for forging. But I think the pro beat the con.

I can agree about the user friendly thing by why would money-only transactions be user friendly?

English is not my native language, so maybe I didn’t deliver my meaning clearly.

Requirement of gems and scrolls in forging items forces players to constant keep those gems and scrolls in inventory or bag of holding. Players have to look out for gems and scrolls which would be needed later when he or she is selling during shopping.
My suggestion is just to get rid of the gems and scrolls requirement and increase the money requirement at the same time. In this way, players can sell gems and scrolls without worrying buying them back or taking care of no selling useful ones. I consider this way of item updating is more user friendly.


PS: I didn’t suggest cancel the requirement of special and unique items as ingredients.

The idea behind gems and scrolls it to add some flavour and sense of why this particular item has that particular effect. However it is understandable that many experienced players dislike excessive inventory management. This is not a new issue, but I haven't found a reasonable solution yet.

I think there are two elements for having non-purely gold based upgrades.

One is flavor, and the second is to gate certain items. For example, requiring Black Blood of Orcus for the ultimate necromancer necklace, Lord of the Underworld, means that a player has to complete (and is incentivized to complete) a very difficult encounter before getting such a powerful item. Philosophically, those types of upgrade items are definitely worth including, and many items in the mod are like that even if not obvious to the player. Bluestone necklaces, scrolls of giant strength, and scrolls of ray of fragmentation come to mind. OK, giant strength is just a rare scroll, but it causes an interesting decision - do I keep the scroll for the item upgrade or do I scribe it to gain access to it? So again worth having.

Random scrolls which are commonly available from merchants, such as haste or death fog, are annoying to track. Similarly, common gems, such as diamonds, emeralds, iol stones, etc., are also annoying to track. In the 2019 era, I'm not sure these are really additive to a player's enjoyment of the game.

There are two solutions that come to mind if Critto and team decides making a change is worthwhile. One is to add a merchant in Cromwell's forge area who sells all of the common gems and scrolls used in crafting for flavor. At the very least, the merchant could buy gems and scrolls and sell them back to the player. In that way the player has a single location to go to get what is needed for a specific crafting item. The second would be to remove them from the crafting requirements and update the dialogue files, but I believe that to be a fair bit of work, so that seems less likely to me.

Removing the items from dialogues is much easier, actually, than implementing a new merchant. I'll consider this as a quality of life feature made as a separate component.
