Drex/N'Garen "ACTION: When attacking this round, you may convert 1 of your [BATTLESTATIONS] results into a [CRITICAL] result and all of your other [BATTLESTATIONS] results into [HIT] results"
If a ship is able to make multiple attacks (Once more into the breach/Secondary torps/etc) does Drex/N'Garen activate on the first attack, converting one BS into a crit and the rest into hits, then on the second attack convert all the BS into hits. Or do they only activate on one attack?
