Item that can change stats on items
IMHO, this will never happen. Sure, it seems like a nice notion at first. I mean, it’s only a luxury item right? Well, Ascended Crafting is a HUGE material sink for the economy. These are the only items this would really benefit, tbh. Outside of Asc. gear, exotics are very affordable. The cheapest item in the Gem store is 35 Gems, I believe. That’s equal to about 5ish gold. That’s Berserker territory and, no offense, if you’re trying to swap Zerker stats then you’re doing it wrong. This year, for Festival of the Four Winds, they brought EVERY crafting material to the chopping block to get them ‘leveled out’. I’m sure some Thick Leather speculators took this as a direct assault, but it seems to me that As. gear just isn’t doing the job as well as they had hoped. I know it sounds nice but, consider the economic impact something small like this could have.
This would stomp on one of the actual game-play reasons for a Legendary Weapon. Doubtful.
Now a single use item that can TRANSFORM an existing exotic to another set of stats (whether a crafted / forged or gem store item), might be possible. Maybe an NPC that can perform this service?
Fate is just the weight of circumstances
That’s the way that lady luck dances
