The greater token gives xp and a title, the lesser gives less xp and no title.
To pick up the advanced token you have to have scored a critical on Bosh Bosh, to pick up the lesser token you just have to be there. A player should be able to obtain and use both the tokens within the week's time that the NPC restricts them to for repeating. Those who get the greater token will be able to pick up the lesser within a reasonable amount of time, so they can assist those who didn't get the greater in getting their greater tokens and be able to pick up the lesser and still receive a reward for helping.
