Hexen: Heresiarch in the Gibbet (Cleric mode) Video

This was played without using any items other than Quartz Flasks and Mystic Urns, on Difficulty 5.

So, the first fight with the Heresiarch. He has 5.000 HP, just as Korax. He can run quite fast but that doesn't matter because most of the time he'll stand there charging up his next attack. His 4 attacks are:
-Shooting out many purple magic orbs at you in a wave-like pattern. These orbs explode when hitting something and can even damage himseld when his shield isn't up
-Throwing 2 burning skull heads which bounce around and home in to you when you're in their "sight". When they hit a wall, they don't vanish like other projectiles, they just bounce off of them as well. After about 30 seconds they vanish by themselves.
-Summoning 2 Mana containers which circle around him and work as a mirror shield, which reflects every projectile. After about 20 seconds the shield dissappears.
-Summoning Dark Bishops (only if he has already lost about 3/4 of his health)

The Cleric's weapons are:
-Mace: A very weak melee weapons. For example, an Ettin needs 6 hits from this weapon to get killed. It's the worst starting weapon of the 3 characters.
-Serpent Staff: It's both a melee and ranged weapon. If used at close range, you drain the HP of the monster in front of you (meaning you get HP when doing this). If you shoot with it, you fire 2 poison projectiles which move a bit like the shots of a Dark Bishop. Uses 1 Blue Mana per shot / drain.
-Firestorm: Fires a beam of fire, when it hits an enemy, fire spreads out in a circle. It's about as strong as the Hammer of Retribution, but a bit weaker. Uses 4 Green Mana per shot.
-Wraithverge: The best weapon in the game! Shoots a ghostly orb, and when it impacts, many ghosts are released which home in to enemies and do heavy damage. Should only be used against hordes of enemies. Uses 18 Green and Blue Mana per shot.
