I've buyied some of the heroes and monster collection pack. oath of the outcast, Crusade of the forgotten etc etc..

At first i though it only will be like reworked miniatures , like the Razor wings that now -THANK GOD- fit in their ONE square space!

But i've noticed that heroes and monsters are abit -sometimes a lot- different from their "Conversion Kit" version.

how it is work? Are like 2 different version you can choose before beginning a quest? are they update version that you are suppose to use to replace the old one? Making pointless the purchase of the "Conversion kit" ? - i mean, sure you can ignore the new expansion, but who really do that with a game like Descent?

-SORRY- nevermind, i just noticed a paper inside the box that syas i'm suppose to Replace the old one with the new one.

Exactly how you do it at your table is up to you, but by RAW, the new heroes and monsters, both models and cards, replace the ones in the Conversion Kit. The Conversion Kit minis and rules are effectively discarded.

I know some people mix them, though, and I know some people prefer the older art or older rules or older minis. But by RAW, the new ones are intended to replace the old ones. It should be covered in the little leaflet that was in the package.

If you buy a H&M pack, you replace the cards that came with the conversion kit. (its in the rules)

yup i noticed, thanks
