This follower can't attack enemies.
At the start of your end phase, do the following 2 times. Roll a 6-sided die. If you roll a 1 or 2, destroy each enemy follower on the field. If you roll a 3 or 4, deal 7 damage to each enemy leader. If you roll a 5 or 6, deal 7 damage to your leader.
QAt the the start of my end phase, I roll the first die of this follower's automatic ability and roll a 3 or 4, dealing 7 damage to each enemy leader. If this brings an opponent's leader's defense to 0 or less, do I win the game without having to resolve the second die roll?
ANo, you must resolve the full ability before Confirmation Timing occurs. It is possible to deal 7 damage to your own leader with the second die, thus resulting in a draw if both you and your opponent's leaders have 0 or less defense.
QCan this follower attack engaged enemy followers?
ANo. "Enemies" refers to both enemy leaders and enemy followers.
