Hello. My name (in-game) is monalisa2247 and i am currently unranked, but i did my 6th provisional as kassa adn with my build i was killing EVERYONE. The game was, ofcourse, a win.

The important part about my masteries is that double-edged sword and spell weaving are COMPLETELY optional, i just take them because those masteries give me a early advantage against other casters(as kassa only).

I take magic pen marks and ap glyphs with ap quints because that means that i can do more dmg as kassa when i have flask.

I take flash and ign just for:

flash: because cmon! Why do you even ask?

Ign: just for the kill potential.

Also, you can take heal just for convinience.

With kassa's new W passive last-hitting has become much, much easier for kassa so creeps will die faster than ever by your hand.

I hope this guide helps you get really good with kassa and get pentas all day, every day.
PEACE!
