if you are getting lower than expected then there is something wrong, 1st is check if your cows(or pets you are using) heal on remote, make it low as low as 100

next, check hp food, if you are using a 200+ hp food, if the cows healed completely then magellan might not cast assist skill to the cows.

My shizune gets 50-80k on 2x, im guessing that buff pets get a little lower on burst.
