Illfang the Kobold Lord

Illfang the Kobold Lord was the boss of Sword Art Online Floor 1.

Background
It took a month, to find the boss, the players were have hard time finding the room, even Kirito, a beta tester was have difficulty. Illfang the Kobold Lord was slain by Kirito, who gave the final blow to the boss, and received the last-attack bonus item, Coat of Midnight.

Abilities
Illfang uses a bone axe and a leather shield to attack, and has four HP bars. Three Ruin Kobold Sentinels spawn and assist the boss at the start, and with the depletion of each of Illfang's HP bars, an additional three Sentinels are spawned (a total of 12).

Once its health is down to 1/3, it will toss the weapons away in favor of a nodachi in which it can use katana skills. Illfang in the Closed Beta Test did not use a nodachi.

Pre-Battle Preparation
The Boss Room was found by Diabel and his six-person party on the 20th level of the First Floor Dungeon. Several meetings were held in Tolbana Town, at which 44 players organized a strategy to face the first boss. They divided themselves into seven parties (six members each, with Kirito and Asuna left over). Groups A and B were heavy armor Tank parties. Groups C-E were high movement Assault parties. Groups F-G were long weapons Support parties. Kirito and Asuna (the eighth party) was delegated to support Group E.

No scouting raids were made, as the information from Argo's handbook was deemed sufficient for the battle.

Strategy
The two Tank parties keep the attention and sustain the pressure of the boss. The Assault Parties C-D would concentrate on the dealing damage to the boss, while the Assault Party E would focus their attention on the sentinels. The Support parties would primarily use the Delay skill to interrupt either the boss's or guards' attacks, and relieve pressure whenever possible.
