When holding triangle button through loadings and a bit after that, the HUD might briefly display some items crystals and gems. CrashRatchet for the handy relic time guide I've supplied a link to and also for having a little argument regarding Powers. Stuff you can do with this "feature" Extra button. But if you want those powers early go ahead, even though there's another way which only works because devs had them all when making those in-game demos, or if you just want every thing, read ahead. The only sort-of exception is Relics, though you need to get any other type than the current to get one more than once.
