There is no High level ascension material from the World, Raid, Titan or Mystic Vision chest.
It’s just very, very, very rare.
I find the B grade for Titans better than A+, so don’t try as hard. I get most ascension items in this order Titan Mystic Raid And World.
Good Luck try shooting for Tier 8…produced most ascension items
This is not good advice. The higher thebtier determines the odds of getting better material. There is no need to artificially hold back.
Rare quests give guaranteed materials. They occur every 10 days or so.
Just stating my experience with Titans. Your mileage may vary. I have designed and coded games for over 4 decades. I can readily see patterns in code.
