Sekhemas Ritual Portal Blocks Projectiles

Noticed that most ritual portals in the Sekhemas Trials seem to block projectiles/caster abilities. I’m not sure if this is intended behavior or a bug, I wanted to see if anyone else has experienced this.

My current build uses Orb of Storms with Arc/Spark. I’ve tested casting from multiple angles, including using Orb of Storms with Magnified Area, which fully covers the portal and the spawned monsters. However, Orb of Storms does not hit or chain to anything, and Arc and Spark either miss entirely or be blocked by the portal itself.

I have to reposition my character constantly and cast dozens of times before killing anything. It’s possible I’m misunderstanding how rituals work, but I don’t have any afflictions that I’m aware of that would prevent damage to monsters. This issue only seems to occur during rituals.
