Editing Midnight Taint Rules (section)

===Tier 3 Marks===
::*  '''Festering''': Vile maggots nest in the rotting skin of the tainted, eating his flesh and destroying his muscle. The tainted channeler suffers 1d3–1 Constitution damage per day (minimum 0). This damage can only be repaired by normal rest, not by spells or other effects. 
::*  '''Hidden Master''': Dark forces swirl about the tainted channeler, corrupted spirits and Lost shades attracted by her vile aura. These entities seek to possess the tainted channeler in moments of weakness. Every time the tainted uses taint points to pay for a spell’s cost, there is a 5% chance per taint point used that an evil trapped spirit (HD equal to the tainted channeler’s caster level + 1 HD per level of the spell that was cast) will attempt to manifest by possessing her body. The tainted channeler may make a Will save as normal to resist the possession, but she suffers a –1 penalty to the save per 5 points of her maximum taint pool, and protection from evil and other defensive measures used to prevent the possession are ineffective.
::*  '''True Madness''':  The tainted channeler teeters on the edge of an abyss of insanity. Every time the tainted channeler uses taint points to pay for a spell’s cost, there is a 5% chance per taint point used that the tainted channeler will be subject to an insanity effect. The tainted channeler may make a Will save as normal to resist the insanity, but she suffers a –1 penalty to the save per 5 points of her maximum taint pool, and mind blank and other defensive measures used to block mind-affecting effects are ineffective. The insanity lasts for a number of days equal to the level of the spell that provoked it.
