So I rolled for Ozzy and only got Nitcoris?

She is good but her niche is mainly for farming due to her high NP charge and chance of insta-kill. As a new player, try to max your main servants first before leveling others.

Nitocris is a top tier farming servant. She can be used even against enemies without class advantage and is one of the most offensive Casters we have at the moment.

Her farming is rather unusual in that she is made to instakill her enemies with the high death chance on her NP and a skill that further boosts it. Also she has another skill which fills her entire NP gauge making it possible to spam it quite frequently.

Besides of being a good farmer and looking really good she is not that useful sadly.

Rolled for Nit, got El-Meloi (my first 5 star!) instead yesterday...well, not complaining. Thank, game.

Her niche is AOE insta-kill via NP+first skill combo, and like Medea she can fill that NP gauge fast, thanks to another skill.

And she has a Guts skill. First skill also gives healing, besides the instant-death boost.

Good for farming (even non-assassin ones, as long as is not full-on Riders), not that useful on many bosses, who usually can't be instant killed.

Nito is a good farming servant with a NP you can spam. I have her at lvl 50 and she can pretty much kill any enemies from the ember farming quests regardless of class affinity.

She's not great for high difficulty content but in terms of farming she's arguably the best in the game. Well being in the opposite situation I'm a bit jealous not that I'll complain about getting Ozzy of course.

Hello! Wall of text incoming!!!

I am "kinda" new compared to other masters here. How long have you play? By the time I write this, it's my 106th day. Pretty much 3.5 months. I already got 2 5* servants, and guess what? I got it in the last two weeks, namely Raikou and Ozy. 1% chance of getting them means it is pure luck. I intend to quit if I can't get one within 4 months, but DW seems to know that. I am F2P, i haven't spend a single penny. Maybe I will spend some, but only for upcoming guaranteed gacha.

Back to Nitocris. I can safely say she is good. Why? Because she as one of minor boss in Camelot campaign managed to insta-kill 2 out of my 6 servants. I never got instakilled in campaign before. And of course, it created total PANIC. I barely beat her, with Beowulf as the last surviving member managed to kick her ass.

Of course, unless you charge her to 500% , insta-kill servant is unlikely. That case before is quite rare.

Don't give up with your FGO. We don't know when luck will strike. My suggestion... Save gacha for servants that you love, not because gameplay, but because you like her/him ideas,graph,cuteness,lore,etc. But if you think today is your lucky day, try to multi roll once/use several tickets, DO NOT "YOLO" saint quartz especially if you fail several times in a row, unless you truly plan to spend all of your gacha on that banner.
Many mobile games make me bored within one month, but I don't plan to stop, not with all of these non stop events and cool story.

Sorry for the wall of text :p
