Guys, just for clarity, we indeed did it first. We did it on Sep 11th and uploaded a vid to bilibili on Sep 12th. Just a bit delay on youtube. U can check the link below for time stamp. www.bilibili.com/video/BV1zT4peDEwQ/
It is impossible since in the pool there are only 9 costs 5 of the same type but if you use the recombulator charm and raise a cost 4 of 3*, it can give you another repeated champion of cost 5 of 3* so you would have to get the same charm and be lucky that when using recombulator it gives you exactly the same cost 5 about 3 times
but there is a bug! you cant equip an item on 1 Cost 4 Star Unit i tried it 3 times. Its not possible. You need to equip the items first bevor 4 Star this champ.
Unfortunately you can’t on that augment. It’s a prismatic and specifically says “gain x unit now and for the next 8 turns gain the same unit” or something along those lines. So you’re only able to get it 3 starred and nothing more.
