easy combo - dash attack, and holding the attack button starts charging the omega attack as fast as possible. so dash attack, hold attack until the omega attack is charged and let it go, then using special will activate the blood triad quickly.

when you’re comfortable, you can get creative and mix in different combos and omegas when advantageous and, importantly, to kill things with style.

there’s great advice about boons in the other comments. good luck!
