Feral Warder Chief

Feral Warder Chief (フィーラル・ワーダーチーフ) was the boss guarding a field dungeon on the 40th Floor of Aincrad in Sword Art Online. The boss had two Hit Point (HP) bars.

Appearance
The Feral Warder Chief was a large jailer monster, in which its head is hidden by a steel mask. Its main weapon consisted of a terrifyingly huge two-handed axe. The monster was only a little over two-meters tall, seeming far smaller when compared to dragon or golem-type boss monsters.

Attack Patterns
The Warder Chief's attack pattern only consisted of physical attacks with its axe, with no area of effect, breath or shock wave attacks; however, differently from the Ruthless Warder Chief, when near death, the boss was capable of using an area of effect attack by gripping its large axe with both hands and making a full rotation with its body as if it were in shot put, assailing the huge tip of the axe in a low trajectory. The direct attack of the techinique would lead into a paralysis debuff.

Strategy
The strategy used by the group of players was to either dodge or block the Feral Warder Chief's attacks and, upon getting an opening, launch up to two-hit Sword Skills, in order to not suffer any lethal counterattacks.
