Viktor is an outstanding champion. he excels in duo lane with another champion with CC keep this in mind as it makes your W easier to hit with.

Pros
- very strong Mid to late game
- Strong Abilities
- AP Supportive Due to WotA

Cons
- Harder Early game
- Can only Out range AD mid through Death Beam

Masteries Are simple AD in offensive and Mana/mana regen in Utility

While building With Viktor I normally rush Will Of The Ancients. The spell vamp really adds up mid game healing for 150+ with every hit of death beam Etc. After buying Sorcerer's Shoes You should Go for Hextech:death As it Gives 45 AP Plus the current bonus From Evolving Technology.
