Fayoum (Boss)

Fayoum is the final boss of the game and appears at the end of the third pyramid. Defeating him will give you the "Its a conspiracy" and the "Fayoum" achievements. Defeating him with the favor of every god (including the Redneck) will give you the "The Gods are nice" achievement. Furthermore, defeating him while having the Plague Medallion or the Cursed Medallion equipped, will give you the achievements "Sudden death" and "One weapon only" respectively.

His combat is made up entirely of one phase with 4 different attacks.

 1. Attack:  He hovers statically between two of the pillars beside the platform launching a barrage of target seeking, relatively slow moving energy balls at you. These balls can either be outrun or shot down, in which case they can drop small ammo-boxes. This phase is usually the best time to deal heavy damage to him, especially with rapid fire weapons.

 2. Attack:  He attaches himself to the edge of the platform for a few seconds and fires a continuous laser-beam which quickly swivels back and forth across the platform (around crotch height). Dodge this attack by jumping over the beam when it approaches you. This attack is usually the second best time to deal damage to him between jumping, especially with high damage, slow shooting weapons (such as some of the pistols).

 3. Attack:  He quickly climbs around one of the pillars on the outside of the platform and hides behind it. He then launches target seeking energy balls at you from behind cover similar to his 1. Attack, only bigger and much more damaging. These can also be either outrun or shot down, in which case they also sometimes drop ammo-boxes. He can only really be damaged at the start of this attack for a second or two while he climbs around the pillar.

 4. Attack:  He 'carpet-bombs' the platform by very quickly flying overhead and dropping "energy-bombs". These will span the entire platform and create a "ghost" or "shadow" on the ground of where they will land and deal damage. Simply position yourself between these "shadows/ghosts" and you should not take any damage. Alternatively, you can also jump of the platform just before the bombs land, and jump back onto it once its over. However this is usually unnecessarily risky and only works with 2 consecutive jumps + Moon Gravity (scroll) or at least 3 jumps. This will however not give you any advantage and just gets stressful, as he usually  'carpet-bombs' 2 or 3 times in a row. You can theoretically hit him while he flies overhead, however getting more then one shot in on him while also managing to dodge the bombs is usually quite difficult and not really worth your HP or the damage dealt.

Remember also that falling off means that you immediately lose the fight!
