Consistent opener for spawning the 2nd moss mother instantly with just n1 and spear.
You just jump and attack, turnaround spear, and then dash and attack once more. The important part is that these 3 hits need to be done before she smashes her head into the ceiling, as it seems she will always spawn the other mother when doing that move so long as enough damage has been taken.
