So for this raid, i found cu to be a nice last resort for the event, i got mostly all the things need to max him and with the bonus ce from this event, he hits pretty hard. So i want to know if i should still grail him? Any suggestion? Thanks
Remember, you won't have an infinite amount of grails. Grailing a servant is just an act of love. Also, servants will benefit from the grail until lvl 90. I personally have my Cu grailed to 90 (with max fou and skills) and he can deal a consistent amount of damage while being immortal. If you grail him to 100, he can solo any boss and survive in the end. Just grail Cu if you want to.
Grail if you like him. Grail if you are planning to use him for a very long time in the front line. It also depends on how many grails you will invest on him, for every level when grailed it gives 115 HP and 84 ATK for him, assuming it is Cu FSN.
He's almost always a nice last resort for everything. Without grails he would do fine tbh, just make sure you max his skills.
