Akali plays as a ninja assassin dashing in and out of battles and dealing tons of damage. She’s intended to be a hybrid damage/ability power champion as her passive gives her bonus damage on attacks depending on ability power but also gives your spells life steel depending on how much damage you’ve built up.
Mark of the assassin is a great harassing and farming tool especially if you can trigger the bonus damage by attacking your target. Twilight shroud is a must have in larger battles.
Mod Skin And Custom Skin
There’s a lot of official skins for Aatrox. You can buy them (if you have the budget) but if you don’t have, you can use the mod skin and custom skin for free.
You just need to download the necessary tools but be minded that only you who can see the actual skin so bear that in mind.
