Lower level sig stones

saddleup

I really like that 5* and 6* sig stones have become a bit easier to get with the rework of milestones but I'm not seeing any 4* and lower sig stones now.
Getting the 2* 3* and 4* sig stones is important for maxing the sig levels of these Champs.
Seems like the only way to build sig level in these Champs is by pulling a dupe from a crystal but with the wide range of Champs in game now there are gonna be Champs that you rarely pull and therefore might never max the sig.

If you want to max out your two and three stars, instead of purchasing the Supreme solo crystals, just focus on the basic solo crystals. You'll get a lot more for your buck and it'll take care of that issue.
