Possible but doing leves all the time is boring IMO, too much needless travelling to camps, mine have been at 99+ for a week now but thats only because Im focusing on Gathering & other achievements and therefore anima is also 100 so I can teleport a lot more when I get lazy.

I used one leve today and the allowance was still 99 so does the allowance max out at some point or will it continue to stack?
