If I come back to the game to level some alts before DF, how long would it take to level with the Winds of Wisdom buff?
For a returning player, reaching max level with the winds of wisdom is usually done in about 10 to 20 hours, depending on how you want to take your time. Veterans and speedrunners can do it in 5 to 9 hours.
This is the fastest it has been in years.
Really fast… I took 3 characters from about level 20 to level 50 in less then a week.
