Cobalt Leader's card text: "When attacking, if the defender is at Range 1 of a bomb token, the defender rolls 1 fewer defense die (to a minimum of 0)."
It seems like the sequence of events provides a narrow scope of effectiveness of this pilot. Correct me if I'm (probably) wrong:
I.
1. Drop thermal detonator / Seismic Charges / Ion Bombs / Bomblet Generator / Proton Bomb
2. End of activation phase detonates
3. beginning of combat phase, bomb is no longer present thus not allowing for trigger card text
II.
1. Drop Cluster Mines / Proximity Mines / Conner Net
2. Enemy ship a. already overlaps when it is dropped b. moves across it
3. bomb detonates
4. beginning of combat phase, bomb is no longer present thus not allowing for trigger card text
III.
1. Drop Cluster Mines / Proximity Mines / Conner Net
2. Nobody overlaps
3. ships in range deal with card text ramifications.
Seems to me that ONLY scenario III allows for the card text to trigger confining the card text to the action bombs thus providing for a pretty narrow strategic window of opportunity. (e.g. cluster mine to detonate leaving the other to trigger the card text, dropping 4 action-bombs all over the board and then circling back to attack ships that are dumb enough to fly within range 1 of them)
