In Phase 2 (when he’s switching between colored attacks), he’s supposed to throw the appropriately colored jewel bomb that matches the color of the attack he’s using. Blue and yellow function this way, but when he uses his green attack, he’ll throw red jewel bombs, and vice versa when he uses his red attack.
There’s no way this is super important, but it’s been this way ever since Gemsbok’s mini-rework a year ago and it’s making me weirdly anxious the longer it goes (seemingly) unnoticed, so I figured I may as well put it on here.
