I would like to meet more drow and demons (not tieflings - demons), and an interesting Dread Necromancer and undead even if he is an NPC. Also interesting is the Aasimar race as positive characters
Thanks to Larian for Baldurs Gate 3 and the reaction to player feedback
Some well known characters of the forgotten realms such as Liriel Baenre ,Jarlaxle, Elminster (maybe disguised as a basic npc), one or more of the seven sisters etc...
A gold dragon or a silver dragon companion that helps the group disguised has a normal humanoid companion ( whatever the class), with multpiple occasions to unmask its true nature via dice/dialogue chacks.
It seems obvious but dragons are an absolute must be. Red dragon would be awesome. I loved Fiirkrag for everything he represented. He was a walking vanity, his wings attack would be epic if only animations weren't so inexistent back then. I would love to see a red dragon just "flush away" my team while slowly walking in the opposite direction.
I always wanted to learn more about Mind Flayers but we kinda have too many of them now lol.
And demons. I loved their riddles.
Alt+ left click in the inventory on an item while the camp stash is opened transfers the item there. Make it a reality.
Orcs and half-orcs! A kenku would also be pretty neat. Also I wanna fight a gelatinous cube, mostly because I have a hard time imagining how a fight like that would work in the game lol.
