They are both gold scrolls if you want one to last longer the odds are that the more expensive one will take longer to get or it will have slightly better base stats than the one from it but odds are we won't see new instance till at least lv 90 in 2.0. If I was spending for power I'd get refine instead

But the real question is whether its worth it compared to when they released gold blade and soon we had ti 81 which had a very similar blade. If we dont get ti 90 soon it will probably be worth more to you.

It's mostly there for people who are desperate to get more power also for there being something to spend for th spend event to get hiruzen otherwise no .
