Anyone have an opinion on which lore store items are must-haves?

Obviously I want them all eventually, but while I can only purchase a select few (of the cheap ones no less), any ones people feel like make the best impact for making your runs better?

Each of the heroes have a special flavor, and is a replacment of the original heroes, but they are not strictly better than the original heroes. If you are having trouble getting past dungeons I'd say purchase the Herbalist, but after learning more and more and becoming better at the game, I found Scholar better (than herblist). Anyway, they are not must-have, but they are interesting.

I'd say Dark Carnival and Night Market are both important places that can heavily influence your gameplay. And they are cheap. Bronze/Silver/Gold statues are also good but they need to be unlocked first. Sacrificing stone is good in Master difficulty as you start the game with you life pool empty and Chaos increases pretty fast.

The items: Boots of Haste and Kuro's Mask are my early game personal favs. Don't go for the expensive ones early if you can't get that far, as they only show up pretty late (at the middle of act 3) in the game.

Trainer in mini-encounters is also nice.
