TL;DR: Click anywhere when the arrow is touching green arc and glowing white, this is for both attacking and combo breaking and is all you have to do (you can also hold down and release, it only registers a click when you release the mouse button) you are sanguine, the red one on the left only click when the arrow is on the green arc (will glow white to indicate) the center top number is the number you need to look at the most, it determines the speed of the attacker the center bottom number isn't necessary, just there to tell you who is attacking, 0 means your turn, 1 means ultra-marine's ultra-marine's attack speed varies on the speed meter, it will be his turn to attack if you miss an attack when it's his turn to attack you need to get the meter to 30 to stop his combo chain
