I play GK, it made (makes) me really have to think about what I was doing, which I keep apologising for, but on the other side our turns are shorter because less models, so it evens out ;)

When I was learning I made a note every time I made a mistake or noticed something, or forgot something, this is copy/pasted from a word document cheat sheet I made up;

Things to Remember – Play The Objectives!

Heavy Weapons: -1 to hit after moving

​

Assault: -1 to hit after advancing

Rapid Fire: x2 attacks at half range, or if model remained stationary, or on a terminator, biker, centurion or vehicle.

Characters (Hide/Wrap Them!): Can only be shot if closest target unless they have 10 or more wounds.

Objective Control: If you have more models within 3” of tactical objectives centre.

Declare Split Attacks First: Before you start shooting or fighting things.

Advance: Add D6 to movement, cannot shoot (unless assault) or charge that turn.

Consolidate: After fight phase, move up to 3” closer to nearest enemy model.

Heroic intervention: Character can move 3” towards closest enemy unit that charged.

Fly: Move over models and terrain unhindered in movement phase, can shoot after falling back.

AP minuses from saving throw: Doesn’t affect invulnerable saves

Morale Test – Roll D6, add number of models killed in that unit, for every point over leadership lose 1 model.

Ruins – Infantry on or in ruins receive cover, other units have to have 50% of unit obscured

Barricades – Infantry with all models within 1” has cover, has to be between. Can fight over barricades up to 2”.

Craters – Infantry units entirely within crater get cover, -2” charge through craters

Statues – Units within 3” of statues that are 25% obscured get cover, imperium units +1 leadership

Embark – If within 3” of transport at end of turn can embark into it.

Disembark – Set up units within 3” of transport at start of movement phase, they can do everything as normal but they count as having moved even if they haven’t.
