Nas'hrah

The Head of the Wizard is a mini-boss in the Blood Pit found by searching in the bloody mess. It's name in the textbox is "Beheaded Wizard".

Its appearance is a floating beheaded head with a moustache and black hair.

Strategy
It is currently believed it is impossible to defeat the Beheaded Wizard or the Ancient Demon.

You only have 5 turns to defeat it before it summons a massive monster (a massive bull), which takes 4 turns to arrive and then instantly kill you. On the first turn, you can attack it and it laughs at you. Then the text box says "Wizard is summoning something from the darkness.." The wizard himself, however, does nothing to hurt you.

Recruiting
(Note: You must also have the Cube of Depths in your inventory, and to have visited the ancient city in order to unlock the special dialogue.)

With the Eclipse Talisman, equip it on your character. Search the bloody mess in the Blood Pit to trigger the battle with Nas'Hrah. Use skill 'Talk', each turn, and he notices the talisman. Correctly answer his questions, and at the last moment he will comment about the cube. Agree to kneel before him and the battle will end, allowing Nas'Hrah to join your party. He can only join your party if you have at least one party member slot available.

Without the talisman and the cube, there is no other way for the Beheaded Wizard to join your party, nor to defeat him or the Ancient Demon. If you initiate combat with him, run from the battle to end the fight with no further penalty. Nas'Hrah disappears afterwards.

Nas'Hrah cannot equip any sort of equipment, they also do not need to eat since they are lacking a body. Having Nash'Hrah in your party unlocks unique dialogue options throughout the game based on the enemies being faced, events being encountered or Gods being fought.

( You obtain the eclipse talisman by talking to the yellow mage, asking about gro-goroth). You will need the Cube of depths as well and to have visited the ancient city before triggering the event.

Lore
The head will introduce itself as Nas'Hrah, the doom and terror of modern man. They will inform the player that they desire to destroy the new Gods and while they could easily kill you and your entire party, they still need your help. You will need to have a empty party slot in order for Nas'Hrah to join you into the ancient city.

It is revealed that Nas'Hrah is yet another, unnamed new God that was betrayed by the other new Gods. Upon confronting three of the four other Gods, Nas'Hrah will have dialogue expanding upon the lore of the game. At this current time, it is unknown if Nas'Hrah actually effects any end game content.

Quotes
Searching the pile : "There is a pile of corpses and guts here.."

Continuing to search the pile : "You have a bad feeling about this.."

Dialogue before fight : "Who disturbs my sleep? Can't you see I have not retained my whole body yet, you INSOLENT FOOL!! I need more fresh blood for the ritual! Kueh keh keh kee!"

Dialogues in fight :

Start of fight : "The floating wizard head chants a prayer.."

When the monster starts to appear : "Beheaded Wizard laughs at you. Kueh keh keh kee! Wizard is summoning something from the darkness.. Something is advancing from the darkness.."

Further into the fight : "A menacing presence is staring at you from the shadows.."

Death : "You feel warm breath of death closing in on you.. The beast in the darkness looks down upon you.. You are crushed with great pressure."

In the newly released V5 of F&H the game has new additional dialogue for the wizard to speak, it is only accessible when having the eclipse talisman in your inventory. At the moment, there is no way to actually persuade the wizard to teach you anything, he will merely laugh at you and continue his spell.
