Part four of my 9th edition Dark Angels codex review will look at the Interromancy Discipline psychic powers that you can add to your army.
Interromancy Discipline
Mind Worm (WC6)- Select one enemy unit within 18", he unit suffers 1 mortal wound. Until the start of the next psychic phase, that unit is not eligible to fight in the Fight phase until all eligible units from your army have done so.
A pretty solid power. The extra mortal wound is nice, but forcing an enemy unit to fight last is really strong against certain army builds. This allows your combat units, such as Black Knights or Terminators, to ensure that they can attack without an enemy unit cutting them down before they get a chance to strike.
Aversion (WC6)- Select an enemy unit within 24". While the unit is within 6" of the Psyker, subtract one from the attacks characteristic of that unit. Any time an attack is made by the unit, subtract 1 from the hit roll.
A good power for de-buffing an enemy unit. Getting -1 to hit is not as strong as it once was, as these can no longer stack, but it can still be pretty powerful. Also strong against melee attacks, where -1 is more difficult to get. Reducing the attacks of the enemy unit is also strong. This doesn't specify reduce the attacks by 1 to a minimum of 1, but I expect this to come in the FAQ. If not, this is really powerful against standard infantry.
This also stacks really well with the Line Unbreakable stratagem. Forcing only enemy models in engagement range to be able to attack, along with -1 to hit and -1 attack really hinders the damage output of an enemy unit and could help your psyker survive or other units survive a powerful enemy melee unit.
