Sorry for all these newbie questions, but I was having trouble finding them in the rulebook.
1. Say during the Melee phase that an Empire disk pinned an Orc disk, but neither was able to inflict enough damage to wound. During the next round, is the Orc disk still considered pinned? Or can he activate as normal to move or attack? And if the Orc can attack, can he attack the disk that was pinning him the previous round?
Disk is pinned as long as another disk is on it.
2. When "command" cards have special abilities that says a hero can do something extra, does it matter if the said hero is already activated? Or can he still do what the command card says? How about when he's pinned? Can the hero still use these special commands bonuses
You can use the abilities of command cards without activation / eminating from already activated disk (unless the card says you have to activate the benefactor of course).
