Your hero enters a Chasm Chamber. Upon drawing, the Dungeon Card pulled is a "Secret Door".
Are you able to cross the Chasm by virtue of the secret door?
The Chasm Chamber states "...On your next turn, you may only exit through a passage on the same side of the Chasm that you entered from. ..."
Secret Door cards says "You may immediately move to any adjacent space. ..."
As written, it seems that it is allowed as the chasm doesn't take effect until "your next turn" and the secret door is "immediate".
