Prologue

You are taken to the Prologue when you first start the game. You fight Boris on a platform as Aatrox with certain skills unlocked. The HUD is hidden during this fight. After either defeating Boris or dying, you are brought to Riot's Dungeon.

Moves available to use:

 * Sweeping Blade
 * Lunge
 * Parry

Taking enough damage will result in:
 * Riposte
 * Umbral Dash
 * Double Jump
 * 1) Losing your wings
 * 2) Breaking your sword, at which point you can no longer hurt him
 * 3) Losing your left hand
 * 4) Losing your right hand as well and dying.

At the start of the fight and upon dealing enough damage, Boris will say the matching quote (listed chronologically):
 * 1) "Our duel begins!"
 * 2) "Your broken form speaks only of failure!"
 * 3) "That broken blade is no match for me!"
 * 4) "I did not think my fellows weak, Aatrox! Already, you disappoint me. To the end of times, I shall kill you again and again. This is your absolution."

The Pause option isn't available during this fight. The game can still be paused by alt-tabbing.

Defeating Boris grants you Sovereign's Crown.
