Do Assault and Shield trigger each combat/showdown or once per turn? Specifically, if Lucian conquers with Assault 1, readies, then attacks again, does he get Assault again? And if a unit with Shield defends, then defends again in the same turn, does Shield apply both times?

Ruling: Assault and Shield do not trigger - they are passive abilities that are either on or off based on the current game state. They can toggle on and off multiple times throughout a turn based on whether the unit is attacking (Assault) or if there are enemy units present (Shield).

Sequence:

• When Lucian attacks as an attacker, Assault is on and grants +1 Might
• After conquering and readying, Lucian is no longer an attacker, so Assault turns off
• If Lucian attacks a second battlefield, he becomes an attacker again and Assault turns back on
• The same applies to Shield - it turns on/off each time combat conditions are met

Nuances:

• Assault and Shield use "while" language ("while I'm attacking"), making them passive static abilities, not triggered abilities
• This is different from triggered abilities that say "when I attack" which would trigger multiple times and stack throughout the turn
• For Assault to be relevant, there must be enemy units present to create a combat situation
• These abilities do not "stack up" over multiple combats in a turn - they simply turn on or off based on current conditions
