Viktor vs Kayle

Poke with Hextech Ray (E), fired in the direction you choose: it hits every enemy in its line, and its upgrade adds an aftershock in its wake.

After Siphon Power (Q), land an auto within 4 seconds: it deals bonus magic damage, and the spell's shield covers you during the trade.

Place Gravity Field (W) in your target's path, then fire Hextech Ray (E): the field slows them, and if they stay in it for 1.25 seconds, they're stunned.

Glorious Evolution (passive) upgrades a spell every 100 Hex Fragments: Hextech Ray (E) to poke and clear, Siphon Power (Q) to survive, Gravity Field (W) to slow.

Place Arcane Storm (R) on grouped enemies: it follows the champions it just damaged on its own, and you can recast it to move it.

Take your trades early: at first, her attack range is a melee champion's, and Divine Ascent (passive) only extends it as she levels up.

Freeze the wave near your tower to keep her off minions: each level empowers her autos through Divine Ascent (passive).

During Divine Judgment (R), hold your damage but use any CC you have: the target can't take damage, but can still be slowed or stunned.

Force objectives and teamfights early on: Kayle gains power with every level, so every minute of the game plays in her favor.
