Hey, I've reviewed the thread in the Starfleet Academy section which contains some amazingly helpful information, but I can't find any hints on how to (for example) train my tactical officer's 'High Yield I' ability to 'High Yield II'. In-game, I have the ensign skill maxed out and promoted him to Lieutenant and am scratching my head, wondering what else I need to do... Is 'High Yield II' a Lieutenant-only skill? Needs to be grabbed from a trainer? I don't know! Helps please!
