It ' s important to understand the history and restrictions in a computational field yours doing research in , but I hope your advisor wasn ' t denigrating . More than anyone they should understand that time is money , and a couple grand for computers out of the research budget is money well spent . <| sep |> I ' ve been on the fence about buying that for a while . You like it ? <| sep |> I usually use shout as my rw , since I don ' t have it . I ' ll consider it if I get ok ' s bsb . Thanks for the suggestion <| sep |> Abilities unlock Extra Skills if the following are all true They have sufficiently high Ability Level for that Extra Skill taphold the Extra Skill icon to see which level that is for each skill . All earlier Extra Skills have been unlocked . The card has been used a certain number of times since the two previous conditions were met this number is a bit vague , but is higher for higherlevel Extra Skills , and can grow quite large . So in short , max out your cards and use them . There ' s a low limit to how many uses count per battle , so no need to spam them excessively , just use them regularly . As for Healer deck , this is a solid writeup .
