"depending on whether or not"
It's also worth remembering this is a legendary, not a regular trinket. I can realistically see it proccing masteries. Just a thought, no need to smash your keyboards.

Thanks for being the only one who didn't go ape on their keyboard, though fyi you'll have the legendary on day 0. The timeless coins drop off the island. From what I can see it'll be from a handful of quests, pickups on the island, and rares dropping keys to the chest hall. There's also a
pet battle quest which drops doubles the prerequisite for the
legendary quest.
