Something that I’m spending a lot of time with is checking to see if an affix is in the codex or not. It’s so complicated to do because you can’t search keywords in the Codex or your Inventory (another suggestion please). You have to look at the item in your inventory, open Codex (which closes the inventory) and then search manually through the Codex to find if that Affix is even in the Codex or not. I know some of us will probably end up learning these by heart later in the game but for new players and casuals, this is brutal.
My suggestion is a little symbol next to the Affix on the item that says if it’s in the Codex and then that symbol is highlighted when you have it unlocked. Just replace the little Gold Star with this symbol. We don’t need a gold star there, the whole affix is written in a different colour.
It would also be helpful to see the item slots an affix can be attached to with a little list of symbols near the affix. Don’t want to get too crazy with symbols all over the place but it would be a huge help early in the game and for casuals. Also a search function in your character’s inventory for Extracted Aspects would be helpful.
Also, to echo the millions of others, please have a Gem Slot in your inventory and make gems take up one square instead of two please. For the love of Sanctuary…PLEASE.
