What do you think does it mean when in each Scenario in the Heroes section it reads "In addition to your Hero Cards, take the following..."
1- You take these 2 minis and complete until 4 heroes of your choice?
2- You can use your any 4 heroes or the suggested in the list of the scenario. It is up to the player to select what he prefers.
What do you think?
For example this:
In addition to your Hero Cards,
take the following:
Danor, Human Wizard: 3
Power 1 Energy Crystals.
Available spells: Flamebolt,
Break Ward, Burn, Feet of
This section is only used when using the standard heroes for that mission. You have your 4 standard hero cards (assuming it is a 4 hero mission or the 2 cards for the two hero missions). Then you added the cards listed specifically to the labeled hero. So Danor gets 3 power 1 crystals, and the 5 spell cards.
If you are playing custom heroes it is sort of up to the Overlord to sort out how items are being transferred between missions and such currently.
