The Chamber of Secrets

The Chamber of Secrets is a Misc. quest given in Year 11. It is part of the main Othaliamus questline, and completing it is required to unlock Focus. 
== Description ==
"After consuming the Unicorn blood, you're now able to enter the Chamber of Secrets and defeat the Basilisk. Othaliamus claims you will lose numbness to an inner part of yourself that keeps you from using focus - a way to cast more powerful magic."
== Objectives ==
# Defeat the Basilisk and awaken your focus
== Walkthrough ==
It is recommended to fight the Basilisk with multiple people, as there are no penalties for doing so, and multiple players can enter the boss room at once (unlike the Egor fight). However, the Basilisk is still doable solo if you can't find anyone to help you.
The Basilisk's weakness is Slashing damage. Slashing spells deal triple damage against the Basilisk. Therefore, you should use spells like: 
* Diffindo (45 damage per crescent/90 dmg)
* Gladio (36 dmg per swing/180 dmg)
* Sectumsempra (45 dmg + debuff)
Other powerful non-Slashing spells are:
* Inpulsa Laqueus (good against large non-player enemies that do not attempt to dodge it)
* Incendio (Very high damage output against enemies that cannot extinguish burning)
* Luminus (high DPS against large enemies due to multiple beam connections)
* Rictusempra (high DPS)
* Encaseum Bombardo (cast on Basilisk's body to trigger instantly, higher damage than Confringo)
However, it is also essential to use mobility spells such as Hastio, Artemio, and Encaseum Porto to dodge the Basilisk's attacks.
When the Basilisk's eyes flash red and it raises its head, look away and make sure your character's back is turned to it. Otherwise, you will become petrified.
In addition to its powerful melee attacks, the Basilisk uses a spitting poison attack that deals tremendous Poison damage and is difficult to dodge. Your best bet is to be moving constantly and avoid having the Basilisk face you.
