On the last part of the Aerin fight, he becomes invincible at 50% HP and you have to end it by hitting him with with Light Dash. After I do this, my Explosive Avoidance eligibility effect changes so that it now has a 90 second expiration. Even if I avoid all barrels, attack him the entire fight, and never leave the top of the rock, I’m not able to kill him before the effect expires.
Is this intentional? It’s frustrating.
