Took me 200+ boxes but I managed to rack up the materials. I have Black Tortoise already perm, but if I craft Shaolin Tiger it's an auto perm.
Black Tortoise RE is a pretty good scroll. It’s Super Art gives you a huge advantage as well if you can land it. It prevents your opponent from attacking for 10 seconds, meaning they’ll have to play defensive during that time.
I wont lie though, I've come to like Shaolin Tiger RE, it has surprisingly good AOE and the b skill is easy to hit if you know when to use it. Been getting top in lobbies alot recently.
