Support / Mage
Nana is a support/mage. Her specialty is Poke/Guard. This means that she can defend the turrets very well and can do damage in a team fight from a distance.
Her main strategy is to use her skills as much as possible, thus reducing her mana very quickly.
Skills, Basic Attack and Durable
First thing that is most crucial is her builds. Below is an example build which is divided into Skills, Basic Attack and Durable. The difference is that skills is used when you tend to use your first skill more than your basic attack.
Basic attack build is when pushing is more your thing rather than kills. Last one is just if you prefer more mana than mana regen.
Durable
is also if you would like to be safe from CCs and Stuns. Emblems may be important. You can use Magic Emblem and select mana regen.
There is also an alternate build for skills. This is for more damage and less lifesteal and slowing enemies.
If you don't really like my builds. you can create your own with the equipment below:
Attack
Rose Gold Meteor Shield for Low HP
Hunter Strike Increase Mobility (never tested)
Blade of Heptaseas (never tested)
Magic
Genius Wand Increase Damage
Lightning Truncheon Increase skill damage
Fleeting Time Decrease CD
Blood Wings More HP and Mana
Clock of Destiny More HP and Mana (not as much)
Calamity Reaper Basic attack has more damage
Glowing Wand Continuous damage with skills
Ice Queen Wand Slow enemies with skills
Concentrated Energy Life Steal
Holy Crystal Percentile Magic Power
Divine Glaive Higher Penetration
Feather of Heaven Quicker attack speed with more magic damage. Useful for late game.
Enchanted Talisman Regenerates max mana in 10 sec
Defense
Twilight Armour Prevent from burst damage
Immortality Insurance
Athena's Shield Shield from Magic Damage
Oracle Increase regen effect
Guardian Helmet Recover HP after fighting
Thunder Belt (never tested)
Queen's Wings Reduce damage done
Movement
Demon Shoes Mana Regen
Rapid Boots Mobility?
Swift Boots Attack Speed
Arcane Boots Magic Penetration
Magic Shoes Reduce CD
Tough Boots Prevent Stun
Roam
Awe Mask Stun with Basic Atk
Courage Mask Team Fight
Shadow Mask Getaway ( useful with Flicker or Sprint)
Spells
Next thing would be her spells. She can use a variety of spells. For her skills build, Revitalise will be needed if mana or HP is short of. Revitalise can also help in team fights to have an advantage over the opponents. For basic attack, maybe inspire or aegis. For durable, flicker would be useful when in sticky situations.
If not, spells that can be use are:
Inspire Push
Sprint Nana may need extra mobility
Revitalise Team fight
Aegis Team fight
Flameshot Poking
Flicker Mobility
Arrival Mobility
Lastly, that would be where she is needed. Her most useful thing would be to irritate opponent junglers. Junglers are usually weak in the early stages, thus preventing them from getting strong too fast. Nana can also defend very well, thus taking care of Mid Lane so that junglers can be guaranteed safety.
