FOR THOSE WHO DON'T KNOW THIS
I just want to share with you guys if you have starlight fragments but you can't afford to buy or you're not interested to have starlight then you must try to use your sl frags you need to exchange it into pass fragments and you may now buy a chest that includes common to epic chessboards.
Tips: if you have sl hero selection chest you can use it to claim 200 sl frags and you can use it to exchange for pass frags (6slhs chest) for the maximum chest (common 12x & epic 12x)
If you buy the chest don't hesitate to maximize it there's a high chance to acquire common to epic chessboards.
*read every pictures for the guides

BUY THIS CHECK MARK CHEST 12X EACH
TIP: MAXIMIZE THE TWO CHESTS USING PASS FRAGS

THIS IS MY CURRENT CHESSBOARDS
1. DEFAULT
2. ACQUIRED USING THE EPIC CHEST
3. BOUGHT USING MAGIC COINS FOR 440,000
4. ACQUIRED USING THE COMMON CHEST

IF YOU HAVE THIS CHEST BOARD AND YOU ALREADY HAVE EVERY HEROES INSIDE THIS CHEST THEN CHOOSE THE SL FRAGS IT GIVES YOU 200 AND YOU CAN USE IT TO EXCHANGE FOR PASS FRAGS
TIP: 8X SL HERO SELECTION CHEST NEEDED TO BUY THE 12X COMMON CHEST & 12X EPIC CHEST TOTAL OF 1,600 PASS FRAGS BUT YOU ONLY NEED 1,440 PASS FRAGS.
COMMON CHEST 40X12 = 480
EPIC CHEST 80X12 = 960
TOTAL OF: 1,440
