Alright guys, shockingly, I haven't played too much 40k in 7th ed. I've been busy but recently, I've been settling in and reading the rulebook but I'm a little uncertain about this new pychic phase thing. Somebody help me out with this please. I roll a D6 at the beginning of the Psychic phase, add the mastery levels of all my psykers and bam, that's how many warp charge points I get? So, if I have a power that's warp charge 2, I can choose to expend 6 warp charge points (assuming I have 6) to use it? Maybe it's simpler than it seems but it's actually quite confusing to me.

Think of charges as dice. You then need a 4+ to manifest this power and a minimum of warp charge cost in successes to manifest it.

You have the basics.

Powers are cast as follows,

1) Decide how many warp charges you wish to use to cast the power.

2) Roll that many dice. For each roll of 4+, one warp charge is successfully harnessed. A power is successfully manifested if you successfully harness an equal or greater number of warp charges to the power's cost. So a power that is cost 2 needs at least 2 successfully harnessed charges.

3) If the power is successfully cast, your opponent may attempt to deny the witch. He rolls any number of his warp charge dice(calculated using the same dice roll and method as warp charges as you generated) to negate the power. Any roll of a 6+ is successful. To stop a power, he must successfully harness a number of warp charges equal to the number that were successfully used to cast the power.


I'm playing GKs and I have a total of 10 mastery levels between all my units on the table. My opponent has a total of 4 mastery levels. My D6 roll is 5. So I generate 15 Warp Charges and my opponent gets 9.

I cast Vortex of Doom. The power is cost 3, so I decide to throw 6 warp charges at it. I successfully harness 4 of them. My opponent will need to get four successful 6+ rolls to deny the power as I successfully got 4 warp charges to cast the power.

The deny the witch roll has modifiers as well, as detailed in the psychic phase section.

Yes you can put 6 charges to try for a power that costs 2 if you wanted. The more dice rolled means the better chance for warp perils though. 6 charges to try for a power that costs 3 perhaps. If you have more charges you can cast another power from the same psyker as long as it's not the same one or use another power known by another psyker. You can keep casting so long as you still have charges and don't cast the same power twice. How much powers are known depends on psyker master level plus various conditional bonuses, character related bonuses and equipment related bonuses. What powers are known is randomly rolled at the begining of the game under the conditioned mentioned in the psykers codex entry. Like which disciplines you have access to for example.

Ah ok, thanks guys. However, how do you "reroll failed psychic tests" then? You just reroll any charge dice that don't get a 4+?

It means if you fail to successfully get enough charges harnessed you can reroll the entire roll.

Psychic tests don't exist anymore. It's a rule from 6th that has no baring on 7th.

Your talking about the Dark Angles Codex right?

Yeah... it's like Tyranids Shadow in the Warp. -3 leadership was supposed to make it harder to cast abilities when casting abilities required a psychic test. Now it will maybe make perils harder if you peril and if you roll the right peril results. ... thanks.

Not really. My Chaos Marine Sorceror can have an upgrade called "spell familiar" that allows him to reroll failed psychic tests. Since psychic tests don't exist anymore, I was wondering how that upgrade would be interpreted in 7th ed.

Alright, that makes sense. Do you know where I can read up on this? Much appreciated man.

Psychic tests weren't removed. They were just changed on how you do them.

REDACTED! pg 25. Apparently it is still called a psychic test.

You fail your test if you don't harness enough warp charges. The only way you can reroll is to reroll all dice, not just the failures.
