Tear of the Goddess (Increases Mana). Next, you should pay attention to whether your mobility champion is enough, our further actions will depend on this. If it is hard for you to dodge the enemy's skills or you want to roam on neighboring lines, then it is better to buy

Blessed Blade: Attacks restore 12 Health on hit.
2200Gunmetal Greaves TIPS: These boots significantly increase Attack Speed while also providing Movement Speed and Lifesteal, making them well suited for champions who rely on frequent basic attacks. Attacking enemy champions temporarily increases Movement Speed, making it easier to chase and reposition, while each hit also restores Health. An excellent choice for auto-attackers who need mobility and consistent sustain in combat.TIPS: Finally, for your items, you should build Youmuu's Ghostblade (Increases Movement Speed) as your first item, followed by Boots of Dynamism (Grants Attack Damage and Armor Penetration) (sometimes it will still be better to build a boot as the first item, which significantly increases the mobility of your champion) the third key element in our build is Muramana (Converts Mana to Attack Damage).
Maybe now it's time to think about upgrading your boot, invest in Gunmetal Greaves (Increases Attack Speed and Movement Speed).
The remaining last three items are situational, of course you can use the example builds above. But for a more effective game you will need to pay attention to the situation on the battlefield.

Crushing Blow: Attacks deal up to 100 bonus magic damage based on Momentum removed. Melee attacks with max Momentum slows by 75% for 1 second.

This makes it an excellent choice for tanks and bruisers who need extra mobility to engage quickly and sustain through fights. Tips: ideal for champions who need to close distance and absorb damage; pairs extremely well with Spellblade items (e.g., Divine Sunderer) for additional burst damage on engage.
