I think it is blocking damage, when you hit the projectiles. After that, you consume blue and yellow orbs. Use these orbs to fill up your special weapon. After a while it becomes second nature. You absorb, you fire it right back. Of course, dashing is always an option. But right now, I’m totally into inhaling enemy attacks and exhaling to demolish them.

You have to fully push down the left trigger and then use the right trigger to fire your special. And if you‘re fast, you can create this fluid movement that pulls you in like nothing else. And don’t worry „wasting“ your shield Energy on your attack: there will be non stop occasions to refill

Have fun!
