The "Rare or better" hero summon item in the store is now "Super Rare or better"
Using "Summon Now" when initially opening Summoning Crystals will now give a guaranteed Card Reset quality hero. So for Shiny Summoning Crystals, it will give a Super Rare or better hero.
Adjustments to drop rates on Summoning Crystals. Lower quality crystals will no longer drop from harder dungeons.
