Build Notes

Build notes and substitutions:
Remember this is a build to play as an assassin.
Boots: Botas de Mana always make after the first item, standard.

Enchantment: Encantamento de Estase is essential, any other enchantment is worse because Diana exposes herself a lot, so she needs something to not die (Encantamento de Estase and Coroa da Rainha Despedaçada).

Spells: Ignite against squishy champions Zoe, Orianna, Viktor, Exhaust against assassins Zed, Talon, Rengar, Cleanse if there are many champions with stun and your comp has no frontline.

Shield cut: swap Tridente da Oceânide for Criafendas if NOT have shield on the enemy team. If they have A LOT shield, you can even make it as second item -> Perdição de Lich > Tridente da Oceânide > Capuz da Morte de Rabadon > Orbe do Infinito > Coroa da Rainha Despedaçada.

Runes: Eletrocutar is essential for assassin along with the red runes. Use Primeiro Ataque if you're very good.
Swap Dilacerar for a defensive green rune if needed: Osso Revestido or Orbe Anulador against assassins, Ventos Revigorantes against poke Orianna, Zyra, Ziggs, Perserverança or Lenda: Tenacidade if they have A LOT stun on the other team Lux, Ahri, Nautilus, Leona, Braum.

Skills: 
Many people are unsure which skill to max after the first Golpe Crescente. Some think the third Zênite Lunar skill is better because of the damage and blah blah blah, but actually the second Cascata Lívida skill is MUCH more beneficial for her than the third Zênite Lunar, besides having a lower Cooldown, the shield she gains is essential for her playstyle.

Playstyle

Play like any assassin, prioritizing champions that don't have much health or defense.
Always focus the enemy adc, mages and peel supports (die, little fairies).

Skins

Winter Blessed is by far her best skin.
Firecracker is the second best skin, if by some miracle it shows up in an event, try to get it.
Sight Ward is the best skin for 990, followed by Serenity Blade, Blood Moon and Infernal.
Lunar Goddess is a one-trick skin and best value for money, Dark Valkyrie is what's left for the noob.
