How did I get only 45 Dungeon tokens?
I believe it is DR. If you do too many dungeon runs in too short of a span of time, you will get DR.
I believe it is more than 4 dungeons in less than 2 hours to hit DR.
I’ve also heard that DR will kick in if you run a dungeon too fast. According to the wiki, completing a single dungeon in 30 minutes may cause DR to kick in.
Did you do any other dungeons before you did Arah. I’ve heard it can cause DR as well.
