After the expiration of the previous Duel Pass, the new Duel Pass for the next 75 days in Master Duel has been introduced. By leveling up the Normal Duel Pass to Level 50, you can obtain the following rewards:
-300 Gems
-30 UR points
-30 SR points
-30 R points
-27 N points
-1 SPYRAL Quik-Fix Icon (at Level 50)

(The amount of rewards is the same, only the icon is new)

The Duel Pass Gold has received some modifications:
-The Duel Pass Gold now costs 700 gems instead of 800 gems.
-The amount of gems you can obtain by leveling up the Duel Pass Gold to Level 100 has been reduced accordingly, for a total of 700 gems, once again matching the initial price you paid for it.
-The amount of crafting points has been reduced accordingly as well:

-100 UR points (from 120)
-100 SR points (from 120)
-80 R points (from 120)
-80 N points (from 112)

Just for reference, the first Duel Pass Gold costed 600 gems, offered 600 gems back, 100 UR points, 100 SR points, 90 R points and 72 N points. Then we got the 800 gems one (returning 800 gems, 120 UR, 120 SR, 120 R and 112 N). So the current one (700 gems, 100 UR, 100 SR, 80 R, 80 N, plus an Icon Frame) is a middle ground between those two.
