|You'd Probably think this is more than a little Mish-Mash, and I guess thats true, but... OK! Gronnblade+ is a great weapon of choice. Nino has the skill naturally, so go for it.
Draw Back is also good - mainly because i've used it to save Fjorm a few times - But if you feel that theres something better for this, please let me know. Sometimes I use Pivot, but thats usually for the jokes.
Dragon Fang is pretty good, but any Attack buffing special will do really. I just had lots of Dragon Fang Fodder, and it is pretty good. Mind the cooldown of 5!
Speaking of +Res, Resistance +3! Negates that "Low" variation from the -Res, so now its just more speed my friend. I would say to do this simply because Nino isn't the most capable defender. She can take a hit, but....
Vantage 3 is hilariously Broken and exploit it. Nino is a murder machine when done right - Hell, the kids outputting more damage then my wrath neph most days.
Breath Of Life is always pretty decent to run, simply due to the consistant heals. Combine that with my (usually wounded) Fjorm In front of Nino as both cover and for the stats, and defensive capabilities don't matter as much.
HP +3 Is just their to reinforce her lifetime. Feel free to mess with this. I think I ended up giving her attack +3 Instead.
- Summoner Support and Ally Support teamed together removes all other defensive issues and turns Nino into a decent defender with good speed and attack rivalling everyone. I mean, this was just funny.
-- I also Gave Nino Water Blessing Via Fjorm to milk some more stats out of it.
(If you want to see a incomplete version of this build, see this Screenshot here - https://imgur.com/a/IyBie)
With Buffs, my base attack from my incomplete build was...
33 + 2 (S slot Atk +2) + 13 (GronnBlade+)+ (S rank Summoner support) = 50
50 + 13 (Summoner Support Bonuses) + 8 (Ally Support Bonuses) +3 (Res +3 A slot) + 2 (Atk +2, A Slot) + 6 (Legendary Effects Via Fjorm) = 82 Base attack. Hoo Boy.
Anyway, have fun and DO YOUR BEST!
