"no success", RNG is RNG. 75 shards could be enough for a furnace, even an ancient one. This thread is stupid.
75 Shards could be enough, but it is very unlikely.
Even though RNG is RNG, there are chances for each event to happen. And based on this chance you can tell, if it is worth it for you to take it or place your bets on something with a much higher chance.
