If you see this then you are very observant. My character name is Corse. Some might know me. I am in Order Of Cross. I use a Strike needle and Winmillion most the time but sometimes Silent nightblade. I really want a 5 * for winmillion and I think it might be coming out soon. (hopefully.) SO should i upgrade my silent nightblade to acheron or strike needle to blitz. I think I would prefer blitz first that way when they come out with the 5 * win. I won't already have a 5 * sword. thoughts and comments please
You might be waiting a long time... the wait for a 5* Troika was just over four months and the upgrades are less than spectacular.
Even if you make your Acheron now, it'll still be useful for jellies/gremlins once a 5* Winmillion appears, so I'd say go for it!
