I do the same and didn't have any issues. Could probably use full force cause it will be at most 300k if I get lucky with my squads and weak attack.

For now I barely spawn anything of my own, just poke others bosses. There is enough of them with refreshing by upgrading with a single manyu or giving single gift, or reloading whole game (if I am out of the previous 2 things).

Will be less "stingy" when I will be done with reissue I am trying to do in background, cause I didn't even start it cause of previous main event stamina hungriness (already done half of it).
