Spellblades and Such: Hexblade

Fixed Hexblade Invading (this time for real)

Reworked Hexblade Magister AI

Magister squads reduced back to 8 members maximum.

Magisters in squads now have ranks associated with them--they will follow the magister that is immediately higher in rank than them when not in combat

Magister Casters have different idle and combat animations

Magister Casters avoid shooting at their teammates and strafe when their line of sight is blocked by a teammate when trying to aim

Magister Casters attempt to leave melee range when engaged in melee by a player.

Magisters no longer move slower when out of melee range

Magisters can now spawn naturally in the darkness either in small groups of up to three, or rarely as entire squads coming out of portals.

Added April Fools/Easter Egg Magus fight, force-able via toggle in the server config file.
