any suggestions or is there anyway how to find fast rare mythstones and crystal?
Go floor 500+ with maxed luck and eternalized/crystaline and nadroji bonus sets. Get crystal/eternal legend every 2-3 maps with pack size and convert for a chance to ultra rare crystal. Mythstones are more rare but they arent used permamently. Asciension perk for luck ans second perk for crystal/eternal legend drop will help also.
but how can i go to floor 500 if in my DQ i only hve 200 floors?
how to find that nadroji item?
You can loot nadroji on floor 200+ from epic+ monsters and at least epic difficulty.
Maps may surpass the normal floor cap
