So, either find some way to cheat the trophy -OR- get someone to lend you a replenisher bomb, which are apparently unforgable from now to eternity… (Word says @Jiivita holds a relic to the past.) Better question is, are you seriously trying to platinum a broken game trophy? I mean… it’s possible… thru… means.
If you’re a trophy collector, I’d like, imagine that legitimacy should hold some value to you. If not, there’s ways. If so… you cannot Platinum Boundless currently. Do with that what you will… bombs or not.
