Editing Warhammer 40,000/Tactics/Psychic 101(8e)

This page indexes how the Psychic Phase works in 8th edition Warhammer 40K.

== Psychic Phase in General ==

Psychic powers are used in their own phase, after moving but before shooting.  Every psyker knows some set of powers, can attempt to manifest some number of powers per friendly Psychic phase, and can attempt to deny some number of psychic powers in each enemy Psychic phase.  In Matched Play, only the ''Smite'' power, which all psykers know by default unless their rules say otherwise, can be spammed; all other powers can only be attempted once per turn.

=== How It Works ===

==== 0: Generating Psychic Powers ====

Psychic powers are generated ''before'' the game starts, but ''after'' list construction (you do not need to commit to your known powers until after you know your enemy's list). A given psyker has access to a certain number of powers from some Discipline, with the Discipline ordinarily set by the model's faction; in addition, unless its rules explicitly say otherwise, all psykers know the ''Smite'' power.  A Discipline has three powers in it, and you may generate your powers by rolling D3s (re-rolling duplicates), or you can simply pick the power(s) your psyker knows, which is what you should always do, as you should be building your list with a clear role for each psyker in it.  

==== 1: Choose Psyker and Power ====
Each psyker in your army may attempt to cast some number of powers, as specified on their datasheet; this number typically varies between 1 (particularly weak) and 3 (particularly strong, and the current maximum).  In addition, in Matched Play, attempting a power blocks out the power for the rest of your army for the turn, except for ''Smite''.  Any psyker who knows a power which has not been blocked and has not reached their attempt limit yet is available to attempt.

==== 2: Casting Powers ====

Roll some number of dice; the number is typically 2, but your psyker's datasheet may say otherwise, such as rolling only 1 die, and various abilities may modify this.  Rarely, you may add or subtract a constant from the rolled value - as usual, your datasheets will indicate this (or, if other models are modifying your rolls, their datasheets).  If you equal or exceed the power's ''warp charge value'', and you live through the attempt (see below), you succeed at the power; otherwise, the power fizzles.

Make sure you record somehow (such as by putting the dice aside, although any additive modifiers do also apply) the result of the dice roll if you succeed; some powers resolve (see below) differently based on your roll.

===== Perils of the Warp =====
''Perils of the Warp'' occurs on any pair of 1s or 6s, aside from any special rules saying otherwise.  When a psyker suffers ''perils of the warp'' for any reason, he suffers 1D3 mortal wounds.  If this kills him, the power fizzles and each unit within 6" suffers D3 mortal wounds.

==== 3: Deny the Witch ====

Any model capable of Deny the Witch (which is any psyker, and certain other models with special rules) within range (24", unless otherwise specified) can attempt to Deny the Witch, up to the number of times specified on their datasheet.  The opposing player (whose Psychic Phases it is not) can nominate any eligible model to attempt to Deny, but only gets one chance to do so.  The Denier rolls their Denial dice - typically 2 - and has to ''exceed'' the total the caster got.  If the Denier does so, the power fizzles.

==== 4: Resolve Power ====

If you made it this far (cast successfully, psyker lived, not denied), resolve the power as specified in the power's rules, as modified by the rules on the psyker, etc.  To give you an idea of how likely this is, here is a table summarizing your chances.

===== Warp Charge Table=====
The following table shows what chance you can expect to cast a power with a given number of warp charges, opposed by a given number of denial dice.  The table assumes Perils kills you, so double sixes is a failure, not a success (and double ones, when the psyker would otherwise succeed).  For a psyker with many wounds, the numbers increase slightly as his ability to live through D3 wounds increases, but not by a drastic amount - the table below remains a good approximation.

Your base chance of getting ''perils of the warp'' on one die is always 0, and on two dice is always 5.56%.
