Playing vs lvl 40 LD is 8 times as expensive as lvl 10 (in terms of colored keys) but really easier
I seriously would like to know the drop rate of each :/
Skills, not cards, are dropped at every level. Specific cards are dropped at specific levels. Amount of cards/skills depends on score. Why is that so hard to comprehend?
I've seen just common sense in the comments so far. The guy wants to know the % of drop @ lvls 10, 20, 30, 40 so he can evaluate the cost/benefict of farming the duelist @ X lvl. That's it.
the drop rate of farming lvl 40 LD is 4.xx% and if you farm lv 30 duelists it's about a 1% chance (for each chest)
in the subreddit is a guy who collected the data of over 500 duels against lv 30 and 40 LDs
