Katarina AD-On-Hit Build Guide: Best Runes & Items for Patch 15.4.1
Katarina is a mechanically intensive assassin who excels at punishing enemy mistakes and snowballing teamfights through her reset-based abilities. Her success rate dramatically increases with player experience, making her an excellent choice for dedicated mains.
Core Mechanics:
- Passive "Voracity" resets ability cooldowns on takedowns
- Dagger pickups deal AOE damage that scales with AD, AP, and on-hit effects
- Ultimate applies on-hit effects and deals both physical and magical damage
- Shunpo (E) acts as an auto-attack reset

Key Strategy Tips:

This champion is ideal for players willing to invest significant time mastering her mechanics and who enjoy an aggressive, reset-based playstyle. While challenging to learn, Katarina can be highly effective up to Master tier when properly mastered.
Note: The article seems to be incomplete in the original content, as it cuts off at "Laning Phase." Without the full original content, I cannot provide the complete rewrite of those sections.
