Nami Support

The Spectral Sickle upgrade. It gives ability power and ability haste, both of which are important stats for Nami, and her poke finishes the quest quickly.

I build Helia as my first main item after boots in most games because it fits Nami's aggressive poke playstyle in lane. Her champion damage stores Soul Fragments, which healing or shielding another ally converts into extra healing. Ebb and Flow (2nd) naturally combines both parts, and her damage in teamfights keeps Helia useful beyond lane. Harmonic Echo can take this slot instead.

I build Ardent second after Echoes of Helia in most games, before Imperial Mandate. Healing or shielding an ally grants attack speed and on-hit damage, so it is especially strong with a hypercarry ADC or several teammates who rely on basic attacks.

Build after Echoes of Helia and Ardent Censer in the default order. Aqua Prison (1st) and Tidal Wave (Ult) apply the mark, increasing damage taken by 7% for 4 seconds. The item grants conditional haste to crowd-control abilities, helping Nami set up another catch.

Staff is a great general item to have that gives ability haste and ability power to you and an ally whenever you heal / shield them. Since it synergizes so well with AP champions, consider building it earlier if you have multiple AP caster champions on your team.

Swap this in for Echoes of Helia when you want extra ally protection without needing to damage enemy champions first. Ebb and Flow (2nd) can spread 30% of healing or 35% of shielding to another nearby ally. If nobody else qualifies, the original target receives the extra protection.

Build this into hard matchups. Against engage tanks and hook supports you are forced to play much safer in lane, so I start Relic Shield over Spectral Sickle for the extra health and the easier activation from behind your minions.

Shurelya's is great for boosting the tempo of your team. It can be used for chasing, running away, or just in teamfights to give your team more engage and sidestepping capabilities. I like pairing this item with champions who rely on movespeed for their combat, like Jinx, Jhin, and Hecarim.

If you are against multiple champions that rely on high shielding to survive, Trident will make it easier for your team to take them down. If your teammates are getting anti-shield, you won't need to.

Against champions with high healing, buy the Oblivion Orb component early in the game, but only upgrade to Morello once you have finished all your other items.

Mikael's is crucial to buy when enemies rely on specific crowd control abilities to lockdown your team. You can also use it to cleanse your carry of a debuff or status effect. When it is needed, I will usually buy Mikael's second or third.

Veil is a super powerful item that blocks the next enemy ability outright. Nami has no dash and no escape, so buy it when the enemy has a hook or a point and click stun that would end your fight before it starts.

Locket provides a shield to all nearby allies, so it is most valuable when against high AOE damage or teamfight focused games.

When you have a single carry that you really need to protect at all costs, Knight's Vow can be bought to help funnel your carry to make them even stronger. This is even more useful against AD teams because of the armor it provides.
