General rules are, aside from "grail for love" :

- the lower the rarity, the more benefit that Servant will get from being grailed

- It's not very cost-efficient to grail SSR to 100

- It's not very cost-efficient to grail support characters (those you use mainly for their team-based skills) to 100
