Quoted from Willy39:Can someone explain Greyjoy to me? When I pick the house what do I do to beat it and what reward do I get? I know it's something about stealing other houses rewards but how does that work? And isn't there something about losing other houses rewards when you pick Greyjoy as well? Like a risk/reward thing? I am a bit confused and almost never battle with Greyjoy.
At the start of ball one, if you pick Greyjoy, here is what happens:
You immediately get credit with completing their house battle, and the right ramp is lit for swords. So collecting that sword unlocks the 4x multipliers right off the bat.
Next, to light other house modes, it is done the same as choosing any other house, hit any of the main 6 shots (7th is GJ, but you already completed that by picking them as your house) 3 times. Once you do that, the center ramp is lit to battle that house. In Greyjoy, when playing a house mode, you will always bring Greyjoy with you, so essentially you can only battle one house at a time.
Once in a mode, they will have a slightly difference path than if you had picked any other house at the start of your game. Each mode will have the typical shots you are used to seeing, with some additional Greyjoy purple shots. Almost every mode requires you to hit these shots IN ADDITION to hitting the normal mode shots in order to complete that house and work your way towards HOTK and IT. The only house mode that does not need the purple shots to be completed is Martell.
Now, if you complete a house mode and light that shield solid, you will get another swords lit at the right ramp. collecting that will increase your multipliers level to 5x. Now you have access to fully multiplied shots. This is the same no matter which house you pick at the start of your game.
What is different about Greyjoy and completing houses, is that you gain that houses power. For example, if you play the Martell mode and beat it, you get an add a ball for the rest of your game. If you complete Tyrell, on inlane lights for combo multiplier increase, and so on.
Hope that helps. Greyjoy is a fun one, and can lead to monster scores!
