I wish to change my 3rd tactical skill on my tactical boff to have torpedo high yield III, im planning on running a plasma torpedo carrier with bops also scoring savage hits with their torpedoes. the best way i know of making the carrier just as deadly as the pets . However as a science officer i can not train this skill, i have looked around on the exchange and all i keep seeing is attack pattern omega I, rapid Fire II, target weapon subsystem III.. but i have yet to see any purple tactical officers with Torpedo High Yield III. i wanted to train one up through my tactical character Servius, however the kicker here is that once i commission the officer i can no longer trade this boff to get the high yield III skill.
how can one science officer get hard to get skills for their boffs?
