So there has been a lot of debate in this thread
about different ideas and tactics. I just wanted to hammer it all out and see what was possible, exploring the different possible tactics behind it. Not to mention it's a great learning experience about the rules. However there seems to be some grave misunderstanding and disagreement about fundamental mechanics of the game here. The very key sequences of a turn seem to be debatable and here is why...
Arriving From Reserve At the start of your Turn Two, ...
This indicates that rolls for reserve happen at the start of your turn, BEFORE the movement phase has begun. This is not to be confused with the "Beginning of your movement phase", as it is even before that happens.
Further evidence of this being true are occassions like when you would roll to see if Nightfighting continues, should that special rule be in effect from a Character's special ability like Imotekh the Stormlord, as per page 55 of the 5th edition Necron Codex "...rolling a D6 at the start of the turn.". Or in a standard mission in which Night Fighting rules did not take effect during game turn 1, as per page 124 of the 6th edition Warhammer 40k Rulebook "...roll a D6 at the start of the Game Turn 5...". Finally, another example is found on page 103 of the White Dwarf containing Codex Sisters of Battle under Miraculous Intervention "Roll a D6 at the start of each of your subsequent turns.". In the final example, Celestine is placed on the board before the Movement phase has occurs and can even be moved any distance until she is 1 inch away from enemy models. She may then move normally during the Movement Phase.
All of these examples illustrate that there is a strong difference between the "Beginning of your turn" and the "Beginning of your movement phase".
But why does this matter?
Well let's take a look at a point brought up by scscofield. He mentioned that a rule on page 125 of the 6th edition Warhammer 40k Rulebook prevented a Librarian from using his powers on the turn he comes into play. However, let's take a look at that rule. "Unless stated otherwise, a unit cannot charge, or use any abilities or special rules that must be used at the start of the turn, in the turn it arrives from reserve.
". User scscofield argues that since a Librarian must use some powers at the "Beginning of his movement phase" he is not permitted to use them if he has come in from reserves, as per the rule on 125. However he is incorrect
since as I have illustrated above, the "Beginning of the movement phase" is NOT the same as the "Beginning of your turn". So, in order for the Librarian to not be able to use said powers, the power would have to read "At the beginning of the turn", which is does, in fact, not
So, are reserve rolls and movement part of the movement phase? This is confusing because the section on the Movement Phase on Page 10 of the 6th edition Warhammer 40k Rulebook says nothing about reserves. How can it be included in a phase which it is not mentioned within?
Which brings us to the most important facet of this discussion. When do reserve rolls and movement take place? Well, interestingly, the new FAQ as per January 13th presents us with a problem. It reads:
Q: Blessings are manifested ‘at the start of the Psyker’s Movement
phase’ – does this mean they happen simultaneously with Reserves
rolls, Outflanking rolls etc and if so which is resolved first? (p68)
A: They do occur simultaneously – as such, the player whose
turn it is decides in what order these things occur as per
page 9 of the Warhammer 40,000 rulebook.
The problem is, who ever presented GW with this question seemed to have the same difficulty in understanding the mechanics behind Arriving from Reserves and Manifesting Powers. This is because page 124 clearly tells us that Reserve Rolls are made BEFORE the movement phase occurs and reads "At the start of your Turn Two, you must roll a d6 for each unit being held...". At the start of your turn, is BEFORE your movement phase. So does that mean that the FAQ is wrong? Did GW even understand what they were saying when they wrote this update? Well, sometimes GW does make odd rulings and even contradict themselves as we have seen.
What can we conclude then about the difference? Could a Librarian arrive from reserve, then use a Blessing at the start of his movement phase since he has not yet acted in it? My conclusion is yes
, he can. Although actions such as Deep Striking and Arriving from Reserves cause the model to "Count as having moved" they did not actually move during the movement phase and despite not being able to further move their normal 6 inches, they can act normally, casting powers or using abilities.
