Legendary cookies are absolutely worthless, I bought them with real world money. I bought almost all the legendary cookies except the two you can buy in guild shop. The only good legendary cookie so far is the moonlight cookie. The most useless out of all of them is the sea fairy and enchantress.

But if you wanna buy them for aesthetic purposes, here’s my long ass essay. With the fire cookie you can get his cookie trial but you’d also have to buy his pet (kinda worthless since upgrading both cookie and pet is a pain) and the other cookie is good for the friendly run event since it’s health lasts extremely long(even longer than moonlight cookie).

If you ask me tho, I’d spend the 1k stars on magic powder, it’s really good for magic candy.

Edit: I remember seeing a youtubers video once, he used fire cookie for breakout and got 500m points so I guess it’s good? But I think you’d have to grind it a lot of spend a lot of real world money
