Is it recommended to try to clear the master missions for this week using the event? or should I try to clear it after?
Nah I don't think you try and use the event to clear this weeks master missions for 2 reasons. For 1 if you are looking for ap efficiency just do singularity 1 and 2 missions, its a lot cheaper than anything in the illya event. My second reasons is that you can just do daily ember farming and you will complete the master missions plus you will get extra embers.
I'm not too concerned about berserkers and golems as there is a quest that can allow me to farm efficiently for them in the illya event. also aware that bone type enemies and saber/lancer enemies can be cleared during ember farming.
how about for ghost type enemies? where would be cheapest in terms of ap to farm them?
