In Rule of Cool’s Legend, there are three “types” of track: “fast” (1st, 3rd, 6th, etc.), “normal” (1st, 4th, 7th, etc.), and “slow” (2nd, 5th, 8th, etc.), and each class has one of each so they cycle through the three tracks, gaining one circle per level (except 1st where they gain two).
Legend characters multi-class by trading one track for a track from another class. For instance, a Barbarian can trade away the Path of Rage track for the Ranger’s Professional Soldier track. Such a character gets Reap the Whirlwind instead of Rage at 1st level, for example.
However, there is no rule that I can find that prevents you from, e.g., trading your “slow” track for another class’s “fast” track. Can you do this? Does this mean you get two circles at each “fast” (and three at 1st!), and no circles at all on the “slow” levels?
Note: I am an avid fan of Legend, and have even had some of my contributions incorporated into Rule of Cool’s products. I have not been compensated for these contributions, and have no financial interest in the success of Rule of Cool or Legend. I merely like the system and want to share my knowledge of it. See this meta question for a discussion of this.
