General Romodi

When determining control of tokens in Fire Lanes, General Romodi would not prevent the removal of a die due to obstruction as this is not an attack against a ship.

Reference

When a ship is attacking another ship, if the attack is obstructed by a ship or obstacle (even if the ship being attacked is also obstructed by a card effect) then the attacking ship may add 1 red die to the attack pool.

After rolling your initial attack pool, then roll 1 red dice into the attack pool.

If the Salvo attack is obstructed by another ship or obstacle and the attacker has General Romodi, then the attacking ship would not lose a die due to obstruction, but it would not add any dice either.

In regards to Early Warning System, General Cracken, and Admiral Montferrat:

If the attacking ship has its commander as General Romodi and it is attacking a ship with one of those cards how does these card effects resolve?

First, if it is an attack from one ship to another, and Line of Sight is not traced over an obstacle or another ship, then those card effects will obstruct the attack. And the attacking ship will lose a die and not gain a die from General Romodi card effect.

However if Line of Sight IS traced over an obstacle or another ship, then General Romodi card effect will allow the attacking ship to not lose a die and it will gain a die.
