Recently unlocked BLU, I understood pretty well what the wiki explained when trying to acquire the spells. My question is, is there a certain time frame where I have to kill the mob right away when the message "mob readies x spell" is seen? Or can I have the luxury of waiting a bit and kill it a couple seconds long after that message is seen? To be honest I don't understand that part of it to well and whether the mob has to die immediately after that notification of the spell being used.

Currently I am using hand to hand and casting dia but I am honestly having no luck getting low level spells. I think I went 1-16 getting the first 4 basic ones without even caring for FOV or ROE quest just straight up single mob grind lol. I came here hoping someone can shed some tips because I feel like I am doing it wrong.

Thank you
