One of the most interesting and exciting parts of the old Darkmatter game was the magic powers characters and villains could have. We've tried to convert these into d20 rules.  Characters receive FX abilities now through having levels in the Adept class.  Each individual ability or spell is treated as a skill.  The old system of FX points has been completely done away with.  Instead the FX cost of the old ability details the DC of the skill check to use the same ability now.  An FX cost of 1 equals DC 15, 2 DC 20, and 3 DC 25.  Also, the old system of ordinary/good/amazing skills has been done away with.  All spells have the same affect now, no matter what the level of success.

Whenever an enemy receives a saving throw, use the character's spell skill check as the DC of the save. Also, anytime a spell calls for a Scry check, the character makes a second roll with that spell's skill.   Some spells get more powerful the better an adept is at casting them.  These bonuses are gained according to a character's rank in that spell, by the Darkmatter book.  The individual details of each kind of special ability are below.  In many respects, the affect of an FX spell has been replaced with a D&D spell.  In this case, retain the old casting times, durations and descriptions of the spell, taking only the affect from the D&D spell.

Diabolism
Diabolism is a set of special abilities, acquired by characters through dark contacts with otherworldly or spiritual powers.  They generally require various kinds of sacrifices.  Some sacrifices provide special bonuses, descriped previously as -1/+1 steps.  Translate these into +2/-2 adjustments to the skill roll required to cast each spell.  The individual description of each Diabolic spell is related below. 
Binding(Cha): this spell translates into three different D&D spells, depending on what type of creature is attempting to be summoned.  Lesser planar binding can be cast with a roll of DC 15,  planar binding with a roll of DC 20, and greater planar binding with a DC of 25.  This is a very powerful spell, but fraught with danger for inexperienced casters, due to the opposed saves and checks required by the spells.
Black Warding(Wis): this spell has affects identical to Mage Armor.
Command(Cha): this spell acts just as the Command spell from the PHB, but retains the original Dark Matter durations, etc.

Tongue of the Damned(Cha): acts as a Contact Other Plane spell.

Enochian Magic
Enochian magic is magic gained by appeals to better powers and mankinds own better nature.  White wizards, so to speak, Enochian spellcasters have a variety of spells and abilities commonly held by Clerics in D&D.  They generally require various kinds of vows.  Some vows provide special bonuses, descriped previously as -1/+1 steps.  Translate these into +2/-2 adjustments to the skill roll required to cast each spell.  The individual description of each Enochian spell is related below. 
Eye of Fate(Wis): this spell has no companion in D&D.  The recipient of this spell gains knowledge of an imminent threat against him in the near future.  When that event is about to occur, the character gains the benefits of the Alertness feat (even if he already has it).
Grace(Wis): treat this spell as a Cat's Grace spell, except that it affects Charisma instead of Dexterity.
