I'm using Charlotte as a riding pet. I'll post the stats of my two Charlotte's so you can see her MATK, but it's not very high. xD
Charlotte Level 50 and 62:
Spoiler:
As for bursting Charlotte with a wind, I have never tried that so I can't really comment on that. But I do know that one of the wind char's skills needs to be replaced with another skill (similar to how water cannot use water shield). If I find out how, I'll post it. (:
