Is it worth grailing a servant with NP1?

My Ibaraki is NP1 grailed to Level 90 and I'm happy to say she's been my main damage dealer on most battles. Coupled that with 10 on her attack skill, she can one shot almost anyone and can shred everyone with a buster brave chain.

The extra stats really help her out due to the Berserker Class' 110% attack modifier. If you love her character go ahead and grail her. Another thing to keep in mind is she's in the regular gacha so another copy of her can always spook you anytime.

I'd say it's worth. Ibaraki is one of the better *4 Zerks, so you made the right choice there.

Grail for love, not utility. All it does is make servants do what they do a little better.

Or for solo memes, in the case of Cu Chulainn.

Some grailing for gameplay, some for their favorite.
He ask for the gameplay purposes, may as well help him to decide the best choice.

Ibaraki can deal massive single target damage even if you just have her at NP 1 and she is very durable berserker with the right team will survive for a long time.

For me i grail for both, i like them and their ability is stronger than most servant with similiar playstyle. So it's a win-win situation.

Pure love, gameplay or both combined. You have 3 choice

Think carefully because grailed is limited, It's up to you to decide later.

I grail for love and gameplay and that is why i have Raiko 100 10/10/10 and Jalter 100 10/10/10
