GM Star Reward Chronicle Sheets for only one character or for each charater?

[陳國光CHEN]

If I have multiple characters, can I apply GM Star Reward Chronicle Sheets to only one character or all my characters?

[Jared Thaler - Personal Opinion]

"Apply the Chronicle sheet to a character of your choice, and unlock new boons as you earn GM stars. 5-Star GMs can apply an additional sheet for every 50 additional reported games they judge beyond their first 150."

One per GM. Until you hit 5 stars.
