|+ Hive Mind
! Number !! Name !! Range !! Target !! Description !! Charge
|-
! 1 !! Dominion
| 36 || Friendly Tyranid Unit with Instinctive Behaviour
| Until the end of your next Psychic phase, target ignores its Instinctive Behaviour ability and automatically passes Morale tests.
| 5
|-
! 2 !! Catalyst
| 18 || Friendly Tyranids Unit
| Until the start of your next Psychic phase, each time a model in target unit suffers a wound '''or mortal wound''', roll a die; on a 5+, the model does not lose a wound.

|-
! 3 !! The Horror
| 24 || Visible Unit
| Until the start of your next Psychic phase, target unit has -1 to hit rolls and Leadership.
| 6
|-
! 4 !! Onslaught
| 18 || Friendly Tyranids Unit
| Target unit can Advance, shoot, and charge this turn, without suffering any penalties to Ballistic Skill, including the usual ones for Heavy and Assault weapons. Note that since you can't cast this until after the Movement phase, you will generally have to Advance the unit you hope to buff, then hope you can get this power onto them.

|-
! 5 !! Paroxysm
| 18 || Enemy Unit
| Until your next Psychic phase, target cannot fight in the Fight phase until all other units that are able to have done so. If the target unit has an ability that allows it to fight first in the Fight phase, it instead fights as if it didn’t have this ability. If both players have units that cannot fight until all other units have done so, then alternate choosing which of those units to fight with, starting with the player whose turn is taking place.

! 6 !! Psychic Scream
| 18 || Closest Enemy Unit
| Target suffers D3 mortal wounds. In addition, if that unit is a Psyker, roll two dice. If the result is higher than their Leadership characteristic, randomly select one of their psychic powers. They can no longer use that psychic power.

|-
! 2 !! Mind Control
| 12 || Enemy Model
| Roll 3D6; if you roll equal to or greater than target model's Leadership, you can make it immediately shoot an enemy unit or make a single close combat attack against it, as if the target were Friendly.  Models cannot attack themselves, but can attack other models in their own unit.
| 6
|-
! 3 !! Psionic Blast
| 18 ||| Visible Enemy Unit
| Roll 2d6. If the result is lower than the highest Leadership in the target, it suffers a mortal wound. Otherwise, it suffers 1d3 mortal wounds.

! 6 !! Might From Beyond
| 18 || Friendly {{W40kKeyword|GENESTEALER CULTS}} {{W40kKeyword|INFANTRY}} or {{W40kKeyword|BIKER}} Unit
| Until the start of your next Psychic phase, target unit has +1 Strength and Attack.  Easily the best power of its kind in the game, having superior range to all of them and a better ratio of return to risk than any of them bar, perhaps, Unleash Rage from Sanguinary (which is -1 Charge for a 12" Attack-only buff).
