Yes, it used to be a flat inside the effective radius, like so many other frames. Then went to whats in front of her in the effected radius, now purely line of sight. So say you see an enemy on a layered multi level area. They jump down, but effectively you would still know they were there. It wont fire. Also casting will still heat up your second ability (but wont cost energy) meanwhile every other frame that has a radius mechanic like this...oh like volt, banshee, citrine, qorvex, saryn, wisp, nova, hydroid, gauss, oberon, etc. They all have an effective radius, effecting all in their area, despite line of sight.
