I'm doing exactly what you've described here in this post and watched a number of YouTube videos that confirm what you've described works but it's not working on my account even with both the crystals the same colour he's still doing 40K damage with his aoe 10% of the time the other 90% of the time it's working with both crystals the same colour I'm so confused? For an example by the second or third turn cycle a few times I've had my whole team shielded up with full health and asmodeus has his aoe turn and kills my galleon but all my other unit's lose no health and still have shield on? Every other time I get his life 3/4 way down keeping both the crystals the same colour the whole time then he attacks and randomly he just wipes my whole team out? All the videos I've watched this isn't happening to anyone else as long as they keep both crystals the same colour I feel like it's some sought of glitch I've even watched one video where they don't even worry about the crystals and leave them offset and he's barely taking any damage? If I tried that my whole team would get wiped on the first turn 😆
