Editing Warhammer 40,000/9th Edition Tactics/Adeptus Mechanicus (section)

===Canticles of the Omnissiah===
At the start of each battle round, you can activate one of the Canticles of the Omnissiah. Each Canticle can only be used once per game.  They affect every unit that has the ability, which is listed on specific datasheets, but in actual practice every {{W40kKeyword|Cult Mechanicus}} unit has the ability and no {{W40kKeyword|Skitarii}} unit does (and no unit has both keywords).

Your army must be 100% Mechanicus (omitting any {{W40kKeyword|Unaligned, Agent of the Imperium}}, or {{W40kKeyword|Knight of the Cog}} units) to make use of these. So, if you want to "soup", you lose out on these. What is really good about Canticles now is that you are choosing them at the "start of each battle round", not on your turn. That means you can declare Shroudpsalm on turn 1 even if your opponent is going first. 

* '''Benediction of the Omnissiah:''' One of the best ones, even if it is a bit redundant. It allows you to re-roll one hit, wound, and damage roll each time the unit shoots. 
**As usual for rules like this, significantly better on smaller units and significantly worse on larger units.
* '''Chant of the Remorseless Fist:''' Add +1 to Strength when attacking in the fight phase, replacing Invocation of Machine Might.
* '''Incantation of the Iron Soul:''' Lets you ignore all penalties to combat attrition checks and mortal wounds on 5+++ (4+++ in Graia's case).
* '''Invocation of Machine Vengeance:''' Roll an additional unkept d6 any time a unit advances or charges.
* '''Litany of the Electromancer:''' Absolutely changed to be more defensive. Any melee attacks against a unit suffer a -1 penalty to hit.
* '''Shroudpsalm:''' Grants army-wide light cover, one of the best canticles. Depending on how much terrain is on the board, it might be best saved for turn 2, when the range closes and lines of sight become easier.
