Misprint at the begining say ...

New Heroes
These new heroes can be easily incorporated into The Tomb of
Ice . Simply shuffle the new heroes in with the others when
choosing heroes at the start of the game.

In AoD and WoD is there Descent: Journeys in the Dark (on base game) instead of The Tomb of Ice . Its illogical .

Previous ToI rules which was published on old site ( was smaller 2,54MB ) contains this misprint too. Btw. this new one D_TOI_Rulesforweb.pdf are bigger ( 25,58MB ) but I still haven't find diferencies between them.
