Legendary shards are the only primary currency, which means it can't be bought from any other. That means you need to treat them as such. If you're getting low, don't burn it all because you ran out of time to get some weapon, so now your last hope is focusing. Resource management, people. You really don't need that weapon so bad that it's worth bankrupting yourself over it. [spoiler]Also I could have said "too lazy to go get it" instead of "because you ran out of time", see I stopped myself lol[/spoiler]
