The Incomplete One

The incomplete one is the first of the three bosses presents in the game.

Attacks

 * Fire Strike (Ranged)
 * Slams hand into ground, causing fire to shoot up in a line toward one side
 * Line continues until barrier is hit, and can be dodged by jumping.

Defense

 * Shout
 * Used at certain HP thresholds to transition to the next phase
 * Stuns player if within range
 * Encases itself in a force field, becoming immune to damage and status effects for a few seconds
 * Damage Field
 * Creates a damaging aura
 * Periodically deals damage to player while in contact, no knock-back
 * Can be rolled through
 * Leap attacks done while this is active cannot be dodged by ducking

Vulnerabilities

 * All attacks have activation frames that you can use to dodge
 * Very vulnerable to magnetic fields, but can still leap at the player
 * He doesn't focus his attacks on turrets, unlike most enemies.
 * Most moves can be cancelled by stunning effects.

Viable Weapons/Skills
All weapons are viable against this boss as long as you know how to dodge. You may want to use turrets and bombs or Spiked Boots to stun him

Fight Strategy

 * Can be easily beaten using magnetic fields and a turret as long as you can dodge attacks.
 * You can use potions when you dodge the leap. Be prepared to dodge again however. You can also use them when he uses his damaging aura by simply running at one side of the arena.
 * Watch out for the Shout as it will stun you long enough to deal some serious damage.
 * You can jump to avoid his hits, but you should not try when he jumps at you or uses his damaging aura, because he can still hit you.
