The problem I'm having is with actions that create the opportunity to play more battle actions, and how they interact with reactions that need to be played in the meantime... Two specific scenarios...
While defending, I use Doomed Intentions to move Bayushi Muhito (w/ an attachment that has a battle action) to a battlefield. The entire effect of Doomed Intentions is to move the personality into battle, straighten it, and then take an additional battle action. So... Do I have to take the Doomed Intentions action before I have a chance to play the Reaction from Muhito, if so, can I still take Muhito's reaction after the Doomed Intention additional action, even though the timing for Muhito's Reaction has passed (that is, he moved into battle a whole action or two ago)? If not, that is, I can play the reaction from Muhito immediately after moving (before the additional Doomed battle action occurs), does that mean that the Doomed Intentions additional battle action is just "waiting on the sidelines" for me to be done with Muhito's Reaction's additional battle action?
The other related question I had, and this one is likely to come up in games, involves Eastern Hub Port. If I have Sneak Attack in hand, and a naval personality in play, and I am attacking. I would like to use my naval reaction to attach an item to one of my naval personalities, then take an additional action due to Eastern Hub Port's trait, and then use Sneak Attack to take an additonal battle action. This sequence of plays does not seem correct, since the Sneak Attack is being played well after its time of "After engaging in a battle" has passed. However, I had no other opportunity to play another reaction after the Naval reaction. Basically, can the reaction window for "after engaging in battle" stay open even after more actions are played (due to naval)?
EDIT:: Card Text Doomed Intentions - Battle: If there are enemy units at the current battlefield: Move one of your target units there. If it moved, straighten it. If you are the Defender, take an additional Battle action printed on a card in the unit.
Bayshi Muhito - Reaction: After an action resolves that moved Muhito to or from a battlefield: Take an additional Battle action.
Eastern Hub Port - Equipping is a Battle/Open action for you. After the first Battle action resolves each turn that attached a card to one of your Personalities: You may take an additional Battle action.
